The system synchronizes the master clock, HD, and VD. The VSP2264 supports all signal terminals that the CCD and the vertical driver require. The R driver and H driver synchronize the A/D converter clock phase to realize ideal performance. The CCD channel has correlated double sampling (CDS) to extract image information from the CCD output signal. The digital control gain curve is linear in dB, ranging from –6 dB to 42 dB.

SLES059—March 2003 VSP2264 5 Introduction 6 VSP2264 SLES059—March 2003 Theory of Operation 2 Theory of Operation 2.1 Introduction The VSP2264 is a high-resolution mixed-signal IC that contains key features associated with the processing of the CCD signal in a digital still camera (DSC). The VSP2264 integrates the analog front end (AFE) and CCD timing generator (TG) with the H and R drivers. The AFE block includes a correlated double sampler (CDS), 14-bit analog-to-digital converter (ADC), digital gain amplifier, black-level clamp loop, input clamp, CDS timing generator, and voltage reference. The built-in TG generates not only horizontal (H-rate) timing, but also vertical (V-rate) timing for the specified CCD model. Optimized timing is generated by selecting the CCD model and operating mode through the serial interface. 2.2 Timing Generator (TG) The TG generates both H-rate timing and V-rate timing. Figure 2–1 shows a high-speed timing block of the TG. This part generates six high-speed pulses for H-rate timing such as R, H1 and HL/H2, SHP/SHD, and ADCCK. These high-speed pulses are generated from the master clock, which has a speed of twice the pixel rate. The serial interface sets the amount of phase adjustment for these high-speed pulses in 16 steps (8 steps for R) with a minimum 0.6-ns pitch (four steps of 0.6 ns and four steps of 1.2 ns for R). The power mode controls the output driver enable/disable. An on-chip decoder calculates H clear according to the CCD model and operating mode. H1, HL, H2, and R can drive the CCD directly. The ADCCK, SHP, and SHD, signals support both the internal generation mode and the external supply mode.

VSP2264 High-Speed Clock Block Diagram 8 VSP2264 SLES059—March 2003 Theory of Operation An on-chip V-rate timing generator creates all the signals that are required for specific CCD image sensors. The TG contains the line and pixel counters used to generate V-rate timing. Figure 2–2 is the block diagram of the line and pixel counter circuit. A maximum 2047 lines and 4095 pixels per line are supported in time scale.

VSP2264 Line and Pixel Counter Block Diagram Figure 2–3 shows a V-rate timing generator block diagram. By one H (horizontal line) before CCD readout, serial data transfer must be completed by the user, and data must be loaded in the registers containing CCD model, operation mode, integration time, and electronic zoom area information. Just before CCD readout, information in the registers is supplied automatically to the decoder, which generates the V-rate signal using line counter and pixel counter data. Not only the signals used for the CCD, but also the strobe light control signal is supported. The CPOB, CLPD, and PBLK signals support both the internal generation mode and the external supply mode.

The AFE circuit includes the correlated double sampler (CDS), a 14-bit analog-to-digital converter (ADC), digital gain amplifier, black-level clamp loop, input clamp, CDS timing generator, and voltage reference. An off-chip emitter-follower buffer or preamplifier is needed between the CCD output and the VSP2264 CCDIN input.

VSP2264 AFE Simplified Block Diagram 2.4 Correlated Double Sampler (CDS) The output signal of a CCD image sensor is sampled twice during one pixel period, once during the reference interval and again during the data interval. Subtracting these two samples extracts the video information of the pixel and removes noise which is low frequency—the kTC and CCD reset noise. Figure 2–5 is a block diagram of the CDS. The CDS is driven through an off-chip coupling capacitor CIN. (A 0.1-µF capacitor is recommended for CIN). AC coupling is highly recommended because the dc level of the CCD output signal is usually too high (several volts) for the CDS to work properly. The appropriate common-mode voltage for the CDS is around 0.5 V–1.5 V. The reference-level sampling is performed while SHP is active, and the voltage level is held on sampling capacitor C1 at the trailing edge of SHP. The data-level sampling is performed while SHD is active, and the voltage level is held on sampling capacitor C2 at the trailing edge of SHD. Then the subtraction of the two levels is performed by the switched-capacitor amplifier. The off-chip emitter follower or equivalent buffer must be able to drive more than 10 pF because the 10-pF sampling capacitor is seen at the input terminal. (Usually additional stray capacitance of a few pF is present.) The analog input signal range of the VSP2264 is about 1 Vp-p.

CDS and Input Clamp Block Diagram 2.5 Input Clamp The buffered CCD output is capacitively coupled to the VSP2264. The input clamp restores the dc component of the input signal which was lost with the ac-coupling and establishes the desired dc bias point for the CDS. Figure 2–5 also shows the block diagram of the input clamp. The input level is clamped to the internal reference voltage CM (1.5 V) during the dummy pixel interval. More specifically, the clamping function becomes active when both CLPD and SHP are active. 2.6 14-Bit A/D Converter The ADC uses a fully differential pipelined architecture of 1.5 bits per stage, which is well-suited for low-power, low-voltage, and high-speed applications. The ADC provides 14-bit resolution for the entire scale. The 1.5-bit-per-stage structure of the ADC is advantageous in realizing better linearity for a smaller signal level. Improved linearity occurs because large linearity errors tend to occur at specific points in the full scale, and the linearity improves for a signal level below any such specific point. 2.7 Digital Programmable-Gain Amplifier (DPGA) Figure 2–6 shows the characteristics of the DPGA gain. The DPGA provides a gain range of –6 dB to 42 dB, which is linear in dB. The gain, controlled by a digital code with 10-bit resolution, can be set through the serial interface; see the Serial Interface Timing Specification (Section 3) for details. The default value of the gain control code is 128 (PGA gain = 0 dB). After powering on, the gain control value is undetermined. For this reason, it must be set to an appropriate value by using the serial interface or reset to the default value by strobing the SYSRST terminal. 12 VSP2264 SLES059—March 2003 Theory of Operation GAIN vs INPUT CODE FOR GAIN CONTROL 50 40 Gain – dB 30 20 10 0 –10 0 100 200 300 400 500 600 700 800 900 1000 Input Code for Gain Control (0 to 1023) Figure 2–6.

Digital PGA and Black-Level Clamp Loop Block Diagram 2.8 AFE Operating Timing The CDS and the ADC are operated by SHP, SHD, and their derivative timing clocks are generated by the internal on-chip timing generator. The DPGA output register and decoder are operated by ADCCK. The digital output data is synchronized with ADCCK. The timing relationship between the CCD signal, SHP, SHD, ADCCK, and the output data is shown in the VSP2264 timing specification. CPOB activates the black-level clamp loop during the OB pixel interval and CLPD activates input clamping during the dummy pixel interval. SLES059—March 2003 VSP2264 13 Theory of Operation 2.9 Black-Level Clamp Loop and 10-Bit DAC To extract the video information correctly, the CCD signal must be referenced to a well-established black level. The VSP2264 has an auto-zero loop (calibration loop) to establish the black level using the CCD optical black (OB) pixels. Figure 2–7 shows the block diagram of this loop. The input signal level from the OB pixels is identified as the real black level, and the loop is closed during this period (actually during the period while CPOB is active). While the auto-zero loop is closed, the difference between the ADC output code is evaluated and applied to the decoder, which then controls the 10-bit current DAC. The current DAC can charge or discharge the external capacitor at COB, depending on the sign of the code difference. The loop adjusts the voltage at COB, which sets the offset of the CDS to make the code difference zero. Thus the ADC output code converges to black level while CPOB is active and maintains the black level derived from the OB pixels after the loop has converged. CPOB performs the OB clamping of both channels simultaneously. To determine the loop time constant, an off-chip capacitor is required and should be connected to the COB terminal. The time constant T is calculated using the following equation: T+ C (16384 I MIN) (1) where C is the capacitor value connected to COB, IMIN is the minimum current (0.15 µA) of the control DAC in the OB level clamp loop, and 0.15 µA is equivalent to 1 LSB of the DAC output current. When C is 0.1 µF, then the time constant T is 40.7 µs for ADC output codes from 0 LSB to 1543 LSB (the convergence curve becomes exponential). For output codes above 1543 LSB, the current DAC injects constant (maximum) current into the capacitor and the convergence curve becomes linear. The slew rate SR is calculated using the following equation. SR + I MAX C (2) where C is the capacitor value connected to COB. IMAX is the maximum current (153 µA) of the control DAC in the OB level clamp loop, and 153 µA is equivalent to 1023 LSB of the DAC output current. Generally, OB level clamping at high speed causes clamping noise. However, the noise can be reduced by making C large. On the other hand, a large C requires a much longer time to restore from the power-save mode or right after the power goes ON. Therefore, 0.1 µF to 0.22 µF is considered a reasonable value for C. If the application environment requires a value outside this range, making careful adjustments by trial and error is recommended. The OB clamp level (the pedestal level) is programmable through the serial interface; see the Serial Interface Timing Specification (Section 3) for details. Also see the Serial Interface Timing Specification section for the relationship between input code and the OB clamp level. The black-level clamp loop not only eliminates the CCD black-level offset, but also eliminates the offsets of the VSP2264 CDS and ADC themselves. 2.10 Preblanking and Data Latency The VSP2264 has a preblanking function. When PBLK = LOW, the digital outputs all become zero at the ninth rising edge of ADCCK, counting from the time when PBLK becomes LOW, to accommodate the clock latency of the VSP2264. Data latency of this device is seven clock cycles. The digital output data come out on the rising edge of ADCCK with a delay of seven clock cycles. Some CCDs have a large transient output signal during blanking intervals. If the input voltage is higher than the supply rail or lower than the ground rail by 0.3 V, then protection diodes are turned on, limiting the input voltage. Such a high-swing signal can cause device damage to the VSP2264 and should be avoided. 14 VSP2264 SLES059—March 2003 Theory of Operation 2.11 Power-Save Mode For the purpose of power savings, the VSP2264 can be put into the power-save plus standby mode by serial interface command. In this mode, all the function blocks are disabled, the A/D outputs all go to zero and the TG output goes to high or low status as determined by the configuration of the serial interface command. The power consumption drops to 39 mW. Because all the bypass capacitors discharge during this mode, a substantial time (usually on the order of 200–300 ms) is required to restore from the power-save plus standby mode. 2.12 Additional Output Delay Control The VSP2264 can control the delay time of output data by setting registers through the serial interface. In some cases, the transition of output data affects analog performance. Generally, this is avoided by adjusting the timing of ADCCK. In case the ADCCK timing cannot be adjusted, the additional output delay control is effective for reducing the influence of transient noise. Refer to the Serial Interface Timing Specification (Section 3) for details. 2.13 Voltage Reference All the reference voltages and bias currents used on the device are created from internal band-gap circuitry. The CDS and the ADC mainly use three reference voltages, REFP (1.75 V), REFN (1.25 V) and CM (1.5 V). REFP and REFN are buffered on-chip. CM is derived as the midvoltage of the resistor chain connecting REFP and REFN internally. The ADC full-scale range is determined by twice the voltage difference between REFP and REFN. REFP, REFN, and CM should be heavily decoupled with appropriate capacitors. Table 2–1.
