LUPA1300−2 Die Photo • Medical Imaging • Industrial Imaging Description conversion, on-chip timing for a wide range of operating modes, and has an LVDS interface for easy system integration. By removing the visually disturbing column patterned noise, this sensor enables building a camera without any offline correction or the need for memory. In addition, the on-chip column FPN correction is more reliable than an offline correction, because it compensates for supply and temperature variations. The sensor requires one master clock for operations up to 500 fps. The LUPA1300-2 is housed in a 168 pin mPGA package and is available in a monochrome version and Bayer (RGB) patterned color filter array. The monochrome version is also available without glass. Contact your local ON Semiconductor office. The LUPA1300-2 is an integrated SXGA high speed, high sensitivity CMOS image sensor. This sensor targets high speed machine vision and industrial monitoring applications. The LUPA1300-2 sensor runs at 500 fps and has triggered and pipelined shutter modes. It packs 24 parallel 10-bit A/D converters with an aggregate conversion rate of 740 MSPS. On-chip digital column FPN correction enables the sensor to output ready to use image data for most applications. To enable simple and reliable system integration, the 12 channels, 1 sync channel, 8 Gbps, and LVDS serial link protocol supports skew correction and serial link integrity monitoring. The peak responsivity of the 14 mm x 14 mm 6T pixel is 63 DN/nJ/cm2. Dynamic range is measured at 57 dB. In full frame video mode, the sensor consumes 1350 mW from the 2.5 V and 3.3 V power supplies.

Unused inputs must always be tied to an appropriate logic level, for example, VDD or GND. All cap_xxx pins must be connected to ground through a 100 nF capacitor. The recommended combinations of supplies are: • Analog group of +2.5 V supply: VSAMPLE, VRES_DS, VMEM_L, VADC, Vpix, VANA, VBUF • Digital Group of +2.5 V supply: VDIG, VLVDS • Combine VPRECH and VRES_AB to one supply (Note 4) Every module in the image sensor has its own power supply and ground. The grounds can be combined externally, but not all power supply inputs may be combined. Some power supplies must be isolated to reduce electrical crosstalk and improve shielding, dynamic range, and output swing. Internal to the image sensor, the ground lines of each module are kept separate to improve shielding and electrical crosstalk between them. The LUPA1300-2 contains circuitry to protect the inputs against damage due to high static voltages or electric fields. However, take normal precautions to avoid voltages higher Table 5.

Therefore, DCD and Jitter tolerance depends on the customer’s system clock generation circuitry. OVERVIEW receive high speed and wide bandwidth data signals and maintain low noise and distortion. A special training mode enables the receiving system to synchronize the incoming data stream when switching to master, slave, or triggered mode. The image sensor also integrates a programmable offset and gain amplifier for each channel. A 10-bit ADC converts the analog signal to a 10-bit digital word stream. The sensor uses a 3-wire Serial Peripheral Interface (SPI). It requires only one master clock for operation up to 500 fps. The sensor is available in a monochrome version or Bayer (RGB) patterned color filter array. It is placed in a 168-pin ceramic mPGA package. Figure 2 depicts the photovoltaic response of the LUPA1300−2. Figure 3 shows the spectral response for the mono and color versions of LUPA1300-2. This data sheet describes the interface of the LUPA1300-2 image sensor. The SXGA resolution CMOS active pixel sensor features synchronous shutter and a maximal frame rate of 500 fps in full resolution. The readout speed is boosted by sub sampling and the windowed region of interest (ROI) readout. FPN correction cannot be used in conjunction with sub-sampling and windowed region of interest readout for windows starting with non zero kernel address. High dynamic range scenes can be captured using the double and multiple slope functionality. User programmable row and column start and stop positions enables windowing. Sub sampling reduces resolution while maintaining the constant field of view and an increased frame rate. The LUPA1300-2 sensor has 12 LVDS high speed outputs that transfer image data over longer distances. This simplifies the surrounding system.

The ADCs nominally operate at 31.5 Msamples/s. Programmable Gain Amplifiers The PGAs amplify the signal before sending it to the ADCs. The amplification inside the PGA is controlled by one SPI setting: afemode [5:3]. Six gain steps can be selected by the afemode register. Table 7 lists the six gain settings. The unity gain selection of the PGA is done by the default afemode setting. Table 8. ADC PARAMETERS Parameter Table 7.

It muxes the outputs of two ADCs to one LVDS block and performs some minor data handling: • CRC calculation and insertion • Training and test pattern generation It also contains a huge part of the functionality for black level calibration and FPN correction. A number of data blocks are placed in parallel to serve all data output channels. One additional channel generates the synchronization protocol. A high level overview is illustrated in the following figure. Figure 8.

It receives a differential clock signal, transmits differential data over the 12 data channels, and transmits a LVDS clock signal and a synchronization signal over the clock and synchronization channel. Figure 9. LVDS Block − High Level Overview The function of this block is to take 10 bits of the protocol block, serialize these bits, and converts them to an LVDS standard (TIA/EIA 644A) compatible differential output signal. The block must also provide a clock to the host, to allow data recovery. This clock is an on-chip version of the clock coming from the host. Sequencer and Logic The sequencer generates the complete internal timing of the pixel array and the readout. The timing can be controlled by the user through the SPI register settings. The sequencer operates on the same clock as the data block. This is a division by 10 of the input clock (internally divided). Table 9 lists the internal registers. These registers are discussed in detail in Detailed Description of Internal Registers on page 15. Table 9.

Uploaded registers have an immediate effect on how the frame is read out. Parameters uploaded during readout may have an undesired effect on the data coming out of the images. AFE Block MBS Block Biasing Block This register block contains registers to shut down ADC channels or the complete AFE block. This block also contains the register for setting the PGA gain: AFE_mode[5:3]. Refer to Absolute Maximum Ratings on page 3 for more details on the PGA settings. The register block contains registers for sensor testing and debugging. All registers in this block must remain unchanged after startup. This block contains several registers for setting biasing currents for the sensor. Default values after startup must remain unchanged for normal operation of the sensor. LVDS Clock Divider Block Image Core Block The registers in this block have an impact on the pixel array itself. Default settings after startup must remain unchanged for normal operation of the image sensor. This block controls division of the input clock for the LVDS transmitters or receivers. This block also enables shutting down one or all LVDS channels. For normal operation, this register block must remain untouched after startup. www.onsemi.com 14 NOIL2SM1300A Data Block Seqmode2[4:0]: Default value after startup is ’10000’, but this must be overwritten with the new value ’10001’ immediately after startup. Seqmode3[6:5]: These two bits set the number of active windows: ‘00’: 1 window ‘01’: 2 windows ‘10’: 3 windows ‘11’: 4 windows (max) Seqmode3. The seqmode3 register consists of the following subregisters: Seqmode3[0]: This bit enables or disables the CRC10 generation on the data and sync channels Seqmode3[1]: Not applicable Seqmode3[2]: Enables or disables column FPN correction Seqmode3[5:3]: Enables or disables, and sets the number of frames grabbed in nondestructive readout mode. ‘000’: Invalid ‘001’: Default, 1 reset, 1 sample ‘010’: 1reset, 2 samples ‘011’: 1 reset, 3 samples Seqmode3[6]: Controls the granularity of the timer settings (only for those that have ‘granularity selectable’ in the description). As a result, all timer settings are set either in number of applied clock cycles, or in the number of ‘readout lines’. ‘0’: expressed in number of lines ‘1’: expressed in clock cycles (multiplied by 2**seqmode4 [3:0]) Seqmode3[7]: Allows syncing of events that happen outside of ROT to be delayed to the next ROT to avoid image artifacts. Seqmode4. This register consists of four subregisters: Seqmode4[3:0]: Multiplier factor (2**seqmode4[3:0]) for the timers when working in clock cycle mode. Seqmode4[5:4]: Selects the source signals to be put on the digital test pins (monitor1, monitor2, and monitor3 pins) “00”: integration time settings “01”: EOS signals “10”: frame sync signals “11”: functional test mode Seqmode4[6]: Enables (1) and disables (0) reverse X read out. Seqmode4[7]: Enables (1) and disables (0) reverse Y read out. Y1_start (60 and 61, 10 bit). These registers set the Y start address for window 1 (default window). X1_start (61, 6bit). This register sets the X start address for window 1 (default window). Y1_end (62 and 63, 10 bit). These registers set the Y end address for window 1 (default window). X1_kernels (63, 6 bit). This register sets the number of kernels or X width to be read out for window 1 (default window). The data block is positioned in between the analog front end (output stage + ADCs) and the LVDS interface. It muxes the outputs of 2 ADCs to one LVDS block and performs some minor data handling: • CRC calculation and insertion. All data can be protected by a 10-bit checksum. The CRC10 is calculated over all pixels between a Line Start and a Line End. It is inserted in the data stream after the line is completed, if input seq_data_crc is enabled.The polynomial used is (x^10+x^9+x^6+x^3+x^2+x+1) and 10 bits are calculated in parallel. When a new line is started, the seed is the first pixel value of a line. No CRC is calculated for that value. From then on, every incoming pixel is updated through the regular CRC. • Training and test pattern generation The most important registers in this block are: Dataconfig. The dataconfig1[7:6] and dataconfig2[7:0] registers insert a training pattern in the LVDS channels to sync the LVDS receivers. Datachannels. DatachannelX_1 and DatachannelX_2 (with X=0 to 12) are registers that allow you to enable or disable the FPN correction (DatachannelX_1[1]), and generate a test pattern if necessary (datachannelX_1[5:4] and datachannelX_2[7:0]). Sequencer Block The sequencer block group registers allow enabling or disabling image sensor features that are driven by the onboard sequencer. This block consists of the following registers: Seqmode1. The seqmode1 registers have the following subregisters: Seqmode1[0]: Enables sequencer for image capture, must be ‘1’ during image acquisition. Seqmode1[1]: This subregister has two modes: ‘1’: In this default mode the integration timing is generated on-chip. ‘0’: In this slave mode, the integration timing must be generated through the int_time1, int_time2, and int_time3 pins. Seqmode1[2]: This bit enables pipelined (0) or triggered (1) mode. Seqmode1[3]: Enable (1) or disable (0) subsampling. Seqmode1[4]: This bit sets the type of subsampling scheme used when subsampling is enabled. ‘1’: Color (1:1:0:0:1:1:0:0:1…) ‘0’: Black and White (1:0:1:0:1) Seqmode1[5]: This bit enables or disables the dual slope integration. Seqmode1[6]: This bit enables or disables the triple slope integration. Seqmode2. The seqmode2 register consists of only two subregisters: www.onsemi.com 15 NOIL2SM1300A Tint_ts_timer (83 and 84). This register sets the length of the triple slope integration time. This value is expressed in ’number of lines’ or in clock cycles (depends on seqmode3[6]). Y2_start (64 and 65, 10 bit). These registers set the Y start address for window 2 (if enabled). X2_start (65, 6bit). This register sets the X start address for window 2 (if enabled). Y2_end (66 and 67, 10 bit). These registers set the Y end address for window 2 (if enabled). X2_kernels (67, 6 bit). This register sets the number of kernels or X width to be read out for window 2 (if enabled). Y3_start (68 and 69, 10 bit). These registers set the Y start address for window 3 (if enabled). X3_start (69, 6bit). This register sets the X start address for window 3 (if enabled). Y3_end (70 and 71, 10 bit). These registers set the Y end address for window 3 (if enabled). X3_kernels (71, 6 bit). This register sets the number of kernels or X width to be read out for window 3 (if enabled). Y4_start (72 and 73, 10 bit). These registers set the Y start address for window 4 (if enabled). X4_start (73, 6bit). This register sets the X start address for window 4 (if enabled). Y4_end (74 and 75, 10 bit). These registers set the Y end address for window 4 (if enabled). X4_kernels (75, 6 bit). This register sets the number of kernels or X width to be read out for window 4 (if enabled). Res_length (76 and 77). This register sets the length of the internal pixel array reset (how long are all pixel reset simultaneously). This value is expressed in ’number of lines’ or in clock cycles (depends on seqmode3[6]). Res_dsts_length. This register sets the length of the internal dual and triple slope reset pulses when enabled. This value is expressed in ’number of lines’ or in clock cycles (depends on seqmode3[6]). Tint_timer (79 and 80). This register sets the length of the integration time. This value is expressed in ’number of lines’ or in clock cycles (depends on seqmode3[6]). Tint_ds_timer (81 and 82). This register sets the length of the dual slope integration time. This value is expressed in ’number of lines’ or in clock cycles (depends on seqmode3[6]). Serial Peripheral Interface (SPI) The serial 4-wire interface (or SPI) uses a serial input or output to shift the data in or out the register buffer. The chip’s configuration registers are accessed from the outside world through the SPI protocol. A 4-wire bus runs over the chip and connects the SPI I/Os with the internal register blocks. To upload the sensor, follow this sequence: Disable Sequencer ® Upload Sensor for new setting ® Enable Sequencer When sequencer is disabled, the training pattern appears on all the channels, including the sync. The interface consists of: • cs_n: chip select, when LOW the chip is selected • clk: the spi clock • in: Master out, Slave in, the serial input of the register • out: Master in, Slave out, the serial output of the register SPI Protocol The information on the data ‘in’ line is: • A command bit C, indicating a write (‘1’) or a read (‘0’) access • 7-bit address • 8-bit data word (in case of a write access) The data ’out’ line is generally in High Z mode, except when a read request is performed. Data is always written on the bus on the falling edge of the clock, and sampled on the rising edge, as seen in Figure 9 and Figure 10. This is valid for both the ’in’ and ’out’ bus. The system clock must be active to keep the SPI uploads stored on the chip. The SPI clock speed must be slower by a factor of 30 when compared to the system clock (315 MHz nominal speed). Figure 10. Write Access (C = ‘1’) The ‘out’ line is held to High Z. The data for the address A is transferred from the shift register to the active register bank (that is, sampled) on a rising edge of cs_n. Only the register block with address A can write its data on the ‘out’ bus. The data on ‘in’ is ignored. Figure 11. Read Access (C = ‘0’) www.onsemi.com 16 NOIL2SM1300A IMAGE SENSOR TIMING AND READOUT Frame Rate and Windowing Frame Rate The frame rate depends on the input clock, the frame overhead time (FOT), and the row overhead time (ROT). The frame period is calculated as follows: 1 kernel = 24 Pixels = 2 Timeslots = 2 Granularity clock cycles Table 10. FRAME RATE PARAMETERS Parameter Comment Clarification FOT Frame Overhead Time Programmable: Default 315 granularity clock cycles (5 ms at 63 MHz) ROT Row Overhead Time Programmable: Default 9 granularity clock cycles (143.1 ns at 63 MHz) Nr. Lines Number of lines read out each frame Number of lines in ROI Nr. Pixels Number of pixels read out each line Number of pixels in ROI Clock Period 1/63 MHz = 15.9 ns Every channel works at 63 MHz ³12 channels result in 756 MHz data rate NOTE: For more information on FPS calculation, refer the ON Semiconductor application note AN57864. In global shutter mode, the whole pixel array is integrated simultaneously including the dummy line for FPN correction. Figure 12. Timing Diagram Windowing Windowing is easily achieved by SPI. The starting point of the x and y address and the window size can be uploaded. The minimum step size in the x-direction is 24 pixels (choose only multiples of 24 as start or stop addresses). The minimum step size in the y-direction is one line (every line can be addressed) in normal mode, and two lines in sub sampling mode. The section Sequencer and Logic on page 11 discusses the use of registers to achieve the desired ROI. Table 11.

The function of each signal is listed in this table. Table 12.

The pixel core is read out line by line after integration. Note that the integration and readout cycle can occur in parallel (refer to Pipelined Shutter on page 20) or in sequential (refer to Triggered Shutter on page 22) mode. In a global shutter, light integration occurs on all pixels in parallel, although subsequent readout is sequential. Figure 12 shows the integration and readout sequence for the global shutter. All pixels are light sensitive at the same period of time.

Global Shutter Operation www.onsemi.com 18 NOIL2SM1300A the pixels are selected in groups of 24 (12 on rising edge, and 12 on the falling edge of the internal clock). So in total, 54 kernels of 24 pixels are read out every line. The internal timing is generated by the sequencer. The sequencer can operate in two modes: master mode and slave mode. In master mode, all internal timing is controlled by the sequencer, based on the SPI settings. In slave mode, the integration timing is directly controlled by over three pins, and the readout timing is still controlled by the sequencer. The seqmode1[1] register of the SPI selects between the master and slave modes. The timing of the sensor consists of two parts. The first part is related to the exposure time and the control of the pixel. The second part is related to the read out of the image sensor. Integration and readout are in parallel or triggered. In the first case, the integration time of frame I is ongoing during the readout of frame I-1. Figure 13 shows this parallel timing structure. The readout of every frame starts with a FOT, during which the analog value on the pixel diode is transferred to the pixel memory element. After this FOT, the sensor is read out line by line. The read out of every line starts with a ROT, during which the pixel value is put on the column lines.

Global Readout Timing (Parallel) Pipelined Shutter with a ROT, during which the pixel value is put on the column lines. Then the pixels are mixed in the correct ADCs, processed, and then sent to the LVDS output block. You have two options in the pipelined shutter mode. The first option is to program the reset and integration through the configuration interface and let the sequencer handle integration time automatically. This mode is called master mode. The second option is to drive the integration time through an external pin. This mode is called slave mode. Integration and readout occur in parallel and are continuous. You only need to start and stop the batch of image captures. Integration of frame N is always ongoing during readout of frame N-1. The readout of every frame starts with a FOT, during which the analog value on the pixel diode is transferred to the pixel memory element. After this FOT, the sensor is read out line by line. The readout of every line starts www.onsemi.com 19 NOIL2SM1300A Table 13 lists the user programmable timer settings and how they are interpreted by the hardware. Programming the Exposure Time In master mode, the exposure time is configured in two distinct methods (controlled by register seqmode3[6]): • # lines: Obvious, changing signals that control integration time. They are always changed during ROT to avoid any image artefacts. • # clock cycles: Must be multiplied by (2**seqmode4[3:0]). When the counter expires, changes are put into effect immediately. Asserting the configuration signal (seqmode3[7]) forces delaying signal updates until the next ROT. Table 13.

The behavior is exactly the same. Master Mode In master mode the reset and exposure time is written in registers. Figure 15. Integration and Image Readout in Master Mode Ensure that the added value of the registers res_length and tint_timer always exceeds the number of lines that are read out. This is because the sequencer samples a new image after integration is complete, without checking if image readout is finished. Enlarging res_length to accommodate for this has no impact on image capture. www.onsemi.com 20 NOIL2SM1300A Slave Mode In slave mode, the register values of res_length and tint_timer are ignored. The integration time is controlled by the int_time pin. The relationship between the input pin and the integration time is shown in Figure 15. When the input pin int_time is asserted, the pixel array goes out of reset and exposure can begin. When int_time goes low again and the desired exposure time is reached, the image is sampled and read out can begin. Figure 16. Integration and Image Readout in Slave Mode Changing pixel’s reset level during line readout might result in image artefacts during a small transient period. As a result, it is advised to only change the value of int_time during ROT. Triggered Shutter The two main differences in the pipelined shutter mode are: • One single image is read upon every user action. • Integration (and read out) is under control of the user through pin int_time. This means that for every frame, you need to manually intervene. The pixel array is kept in reset state until you assert the int_time input. Similar to the pipelined shutter mode, there is a master mode in which the sequencer can control the integration time, or a slave mode in which you can define the integration time. int_time1 Reset Exposure Time N FOT Readout Handling FOT Reset Exposure Time FOT Reset N+1 Readout N FOT Readout N+1 N+1 ROT Line Readout Figure 17. Integration and Readout for Triggered Shutter The possible applications for this triggered shutter mode are: • Synchronize external flash with exposure • Apply extremely long integration times (only in slave mode) www.onsemi.com 21 NOIL2SM1300A Slave Mode Integration time control is identical to the pipelined shutter slave mode. The int_time1 pin controls the start of integration. When int_time is deasserted, the FOT starts (analog value on the pixel diode is transferred to the pixel memory element). Only at that time, image read out can start (similar to the pipelined read out). During read out, the image array is kept in reset. A request for a new frame is started when int_time goes high again. Master Mode In this mode, a rising edge on int_time1 pin is used to trigger the start of integration and read out. The tint_timer defines the integration time independent of the assertion of the input pin int_time1. After the integration time counter runs out, the FOT automatically starts and the image readout is done. During readout, the image array is kept in reset. A request for a new frame is started again when a new rising edge on int_time is detected. The time of the falling edge is not important in this mode. Non Destructive Readout (NDR) time Figure 18. Principle of Non Destructive Readout The sensor can also be read out in a nondestructive method. After a pixel is initially reset, it can be read multiple times, without being reset. You can record the initial reset level and all intermediate signals. High light levels saturate the pixels quickly, but a useful signal is obtained from the early samples. For low light levels, the later or latest samples must be used. Essentially, an active pixel array is read multiple times, and reset only once. The external system intelligence interprets the data. Table 14 on page 23 summarizes the advantages and disadvantages of nondestructive readout. Table 14. ADVANTAGES AND DISADVANTAGES OF NON DESTRUCTIVE READOUT Advantages Disadvantages Low noise, because it is true CDS System memory required to record the reset level and the intermediate samples High sensitivity. The conversion capacitance is kept low. Requires multiples readings of each pixel, so there is higher data throughput High dynamic range. The results include signals for short and long integration times. Requires system level digital calculations Note that the amount of samples taken with one initial reset is programmable in the nr_of_ndr_steps register. If nr_of_ndr_steps is one, the sensor operates in the default method, that is one reset and one sample. This is called the disable nondestructive read out mode. When nr_of_ndr_steps is two, there is one reset and two samples, and so on. In the slave mode, nothing changes on the protocol of the signals int_time_*. The sequencer suppresses the internal reset signal to the pixel array. www.onsemi.com 22 NOIL2SM1300A Image Format and Read Out Protocol The active area read out by the sequencer in full frame mode is shown in Figure 18. Before the actual pixels are read out, one dummy line is read to enable column FPN correction. A reference voltage is applied to the columns and the entire line is read as if real pixel values are placed on the columns. Pixels are always read in multiples of 24 (one value to every channel in the AFE). The last time slot contains not only valid pixels, but also two dummy columns, six grey columns, and eight black columns. Figure 19. Sensor Read Out Format www.onsemi.com 23 NOIL2SM1300A The following sections discuss the appearance of the output (data and synchronization codes) in several relevant configurations. Twelve output channels are connected to the 24 ADCs and handle the data. One additional channel contains all the synchronization codes for the receiver. This indicates, for example, the start of a frame, the end of a frame, whether the data channels contain data, CRC, a training pattern, and so on. The sequencer provides the synchronization channel with the correct synchronization or protocol signals, as shown in Figure 7. The synchronization codes are listed in Table 15. Note that a FS also serves as LS, and vice versa. Table 15.

A clear distinction is made with the single window mode that does not contain the timeslot 54, because the output synchronization protocol is slightly different. Figure 20.

The dummy black line again spans the entire width of the sensor and is processed only once, before all configured windows are read. The dummy black line is independent of the window sizes. www.onsemi.com 27 NOIL2SM1300A ADDITIONAL FEATURES Windowing A fully configurable window can be selected for readout. y start 1024 pixels y end xkernel x start 1280 pixels Figure 24. Window Selected for Readout y_end. The end line of the readout window, granularity of 1. In all cases (even in reverse scan), y_end are larger than y_start. Note that in subsample mode, the correct y_end position must be uploaded (exact value depends on color or B/W subsampling mode). This value must be written to the windowX_3 and windowX_4 register. In case of windowing, the effective readout time is smaller than in full frame mode, because only the relevant part of the image array is accessed. As a result, it is possible to achieve higher frame rates. The parameters to configure this window are: x_start. The sensor reads out 24 pixels in one single clock cycle. The granularity of configuring the X start position is also 24. Every value written to the windowX_2 register must be multiplied by 24 to find the corresponding column in the pixel array. x_kernels. The number of columns that is read out (x_kernels*24 in full frame mode) in subsampling mode x_kernels*48 represents the number of columns over which subsampling is done. The x_kernels value must be written to the windowX_4 register. y_start. The starting line of the readout window, granularity of 1. Note that in subsample mode, the correct y_start position must be uploaded (exact value depends on color or B/W subsampling mode). This value must be written to the windowX_1 and windowx_2 register. Subsampling Subsampling reduces resolution while maintaining the constant field of view and an increased frame rate. LUPA1300-2 supports monochrome and color subsampling modes of operation. The pixel order for one complete row is shown in Table 18 and Table 19 on page 26. www.onsemi.com 28 NOIL2SM1300A Reverse Scan Reverse scanning is supported in the X and Y direction. Line 0 (first line on the output) is the top line in normal mode and the bottom line in reverse scanning, as shown in Figure 24. As a result, the line numbers always increment. When reverse scanning in X, the operation is analogous. To enable reverse readout in X and Y, set the seqmode4[6:7] bits. In addition, the Y_start and X_start addresses must be changed to the new starting address. Figure 25. Normal and Reverse Scanning in Y Multiple Windows windows should be less than or equal to the sum of reset time and integration time. (RTw1+RTw2+RTw3+RTw4) < (Reset time + Integration time). You can configure the number of windows used in the application (one to four). Figure 25 shows how to configure two windows spread over the image array. The sequencer supports the readout of four different windows, randomly positioned over the pixel array. The images are read out sequentially. That is, window 1 is read out before window 2, even if both windows show some overlap. Next, windows 3 and 4 are read out. Each window is treated as a frame and images are read out as shown in Figure 26. Also, the sum of readout times of all four Figure 26.

Exposure and Read Out of Multiple Windows exposure. Without the multiple slope capabilities, the pixels p3 and p4 are saturated before the end of the exposure time, and no signal is received. However, when using multiple slopes, the analog signal is reset to a second or third reset level (lower than the original) before the integration time ends. The analog signal starts decreasing with the same slope as before, and pixels that were saturated before could be nonsaturated at read out time. For pixels that never reach any of the reset levels (for example, p1 and p2) there is no difference between single and multiple slope operation. By choosing the time stamps of the double and triple slope resets (typical at 90% and 99% of the integration, configurable by the user), it is possible to have a nonsaturated pixel value even for pixels that receive a huge amount of light. If the X size of the windows are not identical, the integration time in function of the number of lines read presents multiple slopes (proportional to the X size of these windows). Because this can cause confusion when programming the integration time, it is easier to configure all timer registers using the clock cycle configuration instead of the ’line’ configuration. Multiple Slopes Dynamic range can be extended by the multiple slope capabilities of the sensor. The four colored lines in Figure 28 represent analog signals of the photodiode of four pixels, which decrease as a result of exposure. The slope is determined by the amount of light at each pixel (the more light, the steeper the slope). When the pixels reach the saturation level, the analog does not change despite further Figure 29. Dynamic Range Extended by Multiple Slope Capability www.onsemi.com 30 NOIL2SM1300A The reset levels are configured through external (power) pins. In master mode, the time stamps of the double and triple slope resets are configured in a method similar to configuring the exposure time. The time stamps are enabled through the registers seqmode1[5] and seqmode1[6], and their values are expressed in line or clock cycles in the registers reg_tint_ds_timer and reg_tint_ts_timer. Figure 30. Triple Slope Timing in Master Mode In slave mode, the values of res_length, tint_timer, tint_DS_timer, and tint_TS_timer in the configuration registers are ignored. You have full control through the pins int_time, int_time_ds, and int_time_ts. You must configure the multiple slope parameters for the application and interpret the pixel data accordingly.

The field [1] of Column FPN Correction The column FPN of the sensor is improved by the offset correction of the columns. At the start of every frame, before read out of the actual lines is done, a fixed voltage is applied at the columns and these values are read out like a real data line. Inside the data block, the ’pixel’ data for that line is stored in an on-chip FPN memory. When the correction is enabled, the corresponding FPN value is subtracted from the incoming pixel data. This FPN correction must be enabled for every output separately. The registers used to configure the correction are: these registers enables the offset corrections of the specific output channel. NOTE: Do not change the settings of datachannel12_1. This channel contains synchronization data, not pixel data. If fpn correction is enabled on this channel, the synchronization data becomes corrupt. • seqmode3. The field[2] must be ‘1’. It enables the generation of the line of reference voltages at the columns. Figure 31 and Figure 32 show the effect of enabling the column FPN correction. These images are magnified up to five times.

Full Frame Mode Readout with On Chip Black Level Calibration Disabled Off Chip Automatic Black Level Calibration 2. Set the sensor to safe settings; DACVREFADC must be on a value that never clips the grey (or black) columns. ♦ Make sure that the grey (or black) columns can be read out without clipping. ♦ Make sure that this is the case for every sensor including dc-shifts due to Vt and temperature differences. 3. Read-out the grey (or black) columns. 4. Calculate the average value of this grey (or black) data; also average it out over the different grey columns. 5. Adapt the DACVREFADC if the calculated value deviate from the desired black level value and return to step (2). 6. Repeat the procedure for temperature changes. The last time slot not only contains valid pixels but also two dummy columns, six grey columns, and eight black columns. The grey column values are used to perform off chip black level calibration to maintain a constant black level against any type of drift. These values gauge the response of normal pixels in the dark conditions. Grey columns are generated by applying a minimal integration time (black timer register) to the columns. Black columns share the same minimal integration time; additionally, the pixels in that column are shielded. Grey columns can be used if the integration time is large compared to the minimal integration time. Black columns are used if the integration time is in the same order of magnitude as the minimal integration time. The procedure is as follows: 1. Decide what digital code should be the desired black level. 0x00 cannot be chosen to avoid underflow in FPN correction. www.onsemi.com 33 NOIL2SM1300A PACKAGE Pin List Table 20.
