Agilent ADNB-6031 and ADNB-6032 Low Power Laser Mouse Bundles Datasheet Description The Agilent ADNB-6031 and ADNB-6032 low power laser mouse bundles are the world’s first laser-illuminated system enabled for cordless application. Powered by Agilent LaserStream technology, the mouse can operate on many surfaces that proved difficult for traditional LED-based optical navigation. Its high-performance, low power architecture is capable of sensing high-speed mouse motion while prolonging battery life, two performance areas essential in demanding cordless applications. The ADNS-6030 sensor along with the ADNS-6120 or ADNS6130-001 lens, ADNS-6230-001 clip and ADNV-6330 VCSEL form a complete and compact laser mouse tracking system. There are no moving part, which means high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly. This document will begin with some general information and usage guidelines on the bundle set, followed by individual detailed information on ADNS6030 laser mouse sensor, ADNV-6330 VCSEL, ADNS6120 or ADNS-6130-001 lens and ADNS-6230-001 clip. ADNB-6031 and ADNB-6032 Low Power Laser Mouse Bundles include: Bundle Part Number ADNB-6031 Part Number ADNS-6030 ADNV-6330 ADNS-6120 ADNS-6230-001 Description Low Power Laser Mouse Sensor Single-Mode Vertical-Cavity Surface Emitting Laser (VCSEL) Laser Mouse Round Lens Laser Mouse VCSEL Assembly Clip Bundle Part Number ADNB-6032 Part Number ADNS-6030 ADNV-6330 ADNS-6130-001 ADNS-6230-001 Description Low Power Laser Mouse Sensor Single-Mode Vertical-Cavity Surface Emitting Laser (VCSEL) Laser Mouse Trim Lens Laser Mouse VCSEL Assembly Clip Overview of Laser Mouse Sensor Assembly Figure 1. 2D Assembly drawing of ADNB-6032 (top and cross-sectional view) 2 2D Assembly Drawing of ADNB-6031/32, PCBs and Base Plate *or ADNS-6120 for round lens Figure 2. Exploded view drawing Shown with ADNS-6130-001 Laser Mouse Lens, ADNS6230-001 VCSEL Assembly Clip and ADNV-6330 VCSEL. The components interlock as they are mounted onto defined features on the base plate. The ADNS-6030 laser mouse sensor is designed for mounting on a through hole PCB, looking down. There is an aperture stop and features on the package that align to the lens. The ADNV-6330 VCSEL is recommended for illumination provides a laser diode with a single longitudinal and a single transverse mode. It is particularly suited as lower power consumption and highly coherent replacement of LEDs. It also provides wider operation range while still remaining within single-mode, reliable operating conditions. The ADNS-6120 or ADNS6130-001 Laser Mouse Lens is designed for use with ADNS6030 sensor and the illumination subsystem provided by the assembly clip and the VCSEL. Together with the VCSEL, the lens provides the directed illumination and optical imaging necessary for proper operation of the Laser Mouse Sensor. ADNS-6120 and ADNS-6130-001 are precision molded optical components and should be handled with care to avoid scratching of the optical surfaces. ADNS-6120 also has a large round flange to provide a long creepage path for any ESD events that occur at the opening of the base plate. The ADNS-6230-001 VCSEL Assembly Clip is designed to provide mechanical coupling of the ADNV-6330 VCSEL to the ADNS-6120 or ADNS-6130-001 lens. This coupling is essential to achieve the proper illumination alignment required for the sensor to operate on a wide variety of surfaces. Agilent Technologies provides an IGES file drawing describing the base plate molding features for lens and PCB alignment. 3 Figure 3. Recommended PCB mechanical cutouts and spacing Assembly Recommendation 1. Insert the sensor and all other electrical components into the application PCB (main PCB board and VCSEL PCB board). 2. Wave-solder the entire assembly in a no-wash solder process utilizing a solder fixture. The solder fixture is needed to protect the sensor during the solder process. It also sets the correct sensor-to -PCB distance, as the lead shoulders do not normally rest on the PCB surface. The fixture should be designed to expose the sensor leads to solder while shielding the optical 4 aperture from direct solder contact. 3. Place the lens onto the base plate. 4. Remove the protective kapton tape from the optical aperture of the sensor. Care must be taken to keep contaminants from entering the aperture. 5. Insert the PCB assembly over the lens onto the base plate. The sensor aperture ring should self-align to the lens. The optical position reference for the PCB is set by the base plate and lens. Note that the PCB motion due to button presses must be minimized to maintain optical alignment. 6. Remove the protective cap from the VCSEL. 7. Insert the VCSEL assembly into the lens. 8. Slide the clip in place until it latches. This locks the VCSEL and lens together. 9. Tune the laser output power from the VCSEL to meet the Eye Safe Class I Standard as detailed in the LASER Power Adjustment Procedure. 10. Install the mouse top case. There must be a feature in the top case (or other area) to press down onto the sensor to ensure the sensor and lens are interlocked to the correct vertical height. Design considerations for improving ESD Performance For improved electrostatic discharge performance, typical creepage and clearance distance are shown in the table below.

Schematic Diagram for 3-Button Scroll Wheel Cordless Mouse LASER Drive Mode The laser is driven in pulsed mode during normal operation. A calibration mode is provided which drives the laser in continuous (CW) operation. Eye Safety The ADNS-6030 and the associated components in the schematic of Figure 5 are intended to comply with Class 1 Eye Safety Requirements of IEC 60825-1. Agilent Technologies suggests that manufacturers perform testing to verify eye safety on each mouse. It is also recommended to review possible single fault mechanisms beyond those described below in the section “Single Fault Detection”. Under normal conditions, the ADNS6030 generates the drive current for the laser diode (ADNV-6330). In order to stay below the Class 1 power requirements, LASER_CTRL0 (register 0x1a), LASER_CTRL1 (register 0x1f), LSRPWR_CFG0 (register 0x1c) and LSRPWR_CFG1 (register 0x1d) must be programmed to appropriate values. The system comprised of the ADNS-6030 and ADNV-6330, is designed to maintain the output beam power within Class 1 requirements over components manufacturing tolerances and the recommended temperature range when adjusted per the procedure below and implemented as shown in the recommended application circuit of Figure 5. For more information, please refer to Agilent ADNB-6031 and ADNB-6032 Laser Mouse Sensor Eye Safety Application Note AN 5230. LASER Power Adjustment Procedure 1. The ambient temperature should be 25C +/- 5C. 2. Set VDD t o its permanent value. 3. Set the Range bit (bit 7 of register 0x1a) to 0. 4. Set the Range_C complement bit (bit 7 of register 0x1f) to 1. 5. Set the Match_bit (bit 5 of register 0x1a) to the correct value for the bin designation of the laser being used. 6. Set the Match_C_bit (bit 5 of register 0x1f) to the complement of the Match_bit. 7. Enable the Calibration mode by writing to bits [3,2,1] of register 0x1A so the laser will be driven with 100% duty cycle. 8. Write the Calibration mode complement bits to register 0x1f. 9. Set the laser current to the minimum value by writing 0x00 to register 0x1c, and the complementary value 0xFF to register 0x1d. 10. Program registers 0x1c and 0x1d with increasing values to achieve an output power as close to 506uW as possible without exceeding it. If this power is obtained, the calibration is complete, skip to step 14. 11. If it was not possible to achieve the power target, set the laser current to the minimum value by writing 0x00 to register 0x1c, and the complementary value 0xff to register 0x1d. 12. Set the Range and Range_C bits in registers 0x1a and 0x1f, respectively, to choose to the higher laser current range. 13. Program registers 0x1c and 0x1d with increasing values to achieve an output power as close to 506uW as possible without exceeding it. 14. Save the value of registers 0x1a, 0x1c, 0x1d, and 0x1f in non-volatile memory in the mouse. These registers must be restored to these values every time the ADNS-6030 is reset. 15. Reset the mouse, reload the register values from non-volatile memory, enable Calibration mode, and measure the laser power to verify that the calibration is correct. Good engineering practices such as regular power meter calibration, random quality assurance retest of calibrated mice, etc. should be used to guarantee performance, reliability and safety for the product design. 7 LASER Output Power The laser beam output power as measured at the navigation surface plane is specified below. The following conditions apply: 1. The system is adjusted according to the above procedure. 2. The system is operated within the recommended operating temperature range. 3. The VDD v alue is no greater than 300mV above its value at the time of adjustment. 4. No allowance for optical power meter accuracy is assumed. Disabling the LASER LASER_NEN is connected to the gate of a P-channel MOSFET transistor which when ON connects VDD t o the LASER. In normal operation, LASER_NEN is low. In the case of a fault condition (ground or VDD a t XY_LASER), LASER_NEN goes high to turn the transistor off and disconnect VDD f rom the LASER. Single Fault Detection ADNS-6030 is able to detect a short circuit or fault condition at the XY_LASER pin, which could lead to excessive laser power output. A path to ground on this pin will trigger the fault detection circuit, which will turn off the laser drive current source and set the LASER_NEN output high. When used in combination with external components as shown in the block diagram below, the system will prevent excess laser power for a resistive path to ground at XY_LASER by shutting off the laser. In addition to the ground path fault detection described above, the fault detection circuit is continuously checked for proper operation by internally generating a path to ground with the laser turned off via LASER_NEN. If the XY_LASER pin is shorted to VDD, this test will fail and will be reported as a fault.

Single Fault Detection and Eye-safety Feature Block Diagram 8 Agilent ADNS-6030 Laser Mouse Sensor Features • Low power architecture Theory of Operation The ADNS-6030 is based on LaserStream Technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. The ADNS-6030 contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), and a four wire serial port. The IAS acquires microscopic surface images via the lens and illumination system. These images are processed by the DSP to determine the direction and distance of motion. The DSP calculates the ∆x and ∆y relative displacement values. An external microcontroller reads the ∆x and ∆y information from the sensor serial port. The microcontroller then translates the data into PS2, USB, or RF signals before sending them to the host PC or game console.

Wavelength Responsivity 15 Power management modes The ADNS-6030 has three power-saving modes. Each mode has a different motion detection period, affecting response time to mouse motion (Response Time). The sensor automatically changes to the appropriate mode, depending on the time since the last reported motion (Downshift Time). The parameters of each mode are shown in the following table. Synchronous Serial Port The synchronous serial port is used to set and read parameters in the ADNS-6030, and to read out the motion information. The port is a four-wire port. The host micro-controller always initiates communication; the ADNS-6030 never initiates data transfers. SCLK, MOSI, and NCS may be driven directly by a micro-controller. The port pins may be shared with other SPI slave devices. When the NCS pin is high, the inputs are ignored and the output is tri-stated. The lines that comprise the SPI port: SCLK: Clock input. It is always generated by the master (the micro-controller). MOSI: Input data. (Master Out/Slave In) MISO: Output data. (Master In/Slave Out) NCS: Chip select input (active low). NCS needs to be low to activate the serial port; otherwise, MISO will be high Z, and MOSI & SCLK will be ignored. NCS can also be used to reset the serial port in case of an error. Chip Select Operation The serial port is activated after NCS goes low. If NCS is raised during a transaction, the entire transaction is aborted and the serial port will be reset. This is true for all transactions. After a transaction is aborted, the normal address-to-data or transaction-to-transaction delay is still required before beginning the next transaction. To improve communication reliability, all serial transactions should be framed by NCS. In other words, the port should not remain enabled during periods of nonuse because ESD and EFT/B events could be interpreted as serial communication and put the chip into an unknown state. In addition, NCS must be raised after each burstmode transaction is complete to terminate burst-mode. The port is not available for further use until burst-mode is terminated. Mode Rest 1 Rest 2 Rest 3 Response Time (nominal) 33ms 164ms 840ms Downshift Time (nominal) 237ms 8.4s 504s Motion Pin Timing The motion pin is a levelsensitive output that signals the micro-controller when motion has occurred. The motion pin is lowered whenever the motion bit is set; in other words, whenever there is data in the Delta_X or Delta_Y registers. Clearing the motion bit (by reading Delta_X and Delta_Y, or writing to the Motion register) will put the motion pin high. LASER Mode For power savings, the VCSEL will not be continuously on. ADNS-6030 will flash the VCSEL only when needed. 16 Write Operation Write operation, defined as data going from the microcontroller to the ADNS-6030, is always initiated by the micro-controller and consists of two bytes. The first byte contains the address (seven bits) and has a “1” as its MSB to indicate data direction. The second byte contains the data. The ADNS-6030 reads MOSI on rising edges of SCLK. SCLK t DLY-MISO MISO D0 t HOLD-MISO Read Operation A read operation, defined as data going from the ADNS6030 to the micro-controller, is always initiated by the microcontroller and consists of two bytes. The first byte contains the address, is sent by the micro-controller over MOSI, and has a “0” as its MSB to indicate data direction. The second byte contains the data and is driven by the ADNS6030 over MISO. The sensor outputs MISO bits on falling edges of SCLK and samples MOSI bits on every rising edge of SCLK. Note: The 0.5/fSCLK minimums high state of SCLK is also the minimum MISO data hold time of the ADNS-6030. Since the falling edge of SCLK is actually the start of the next read or write command, the ADNS6030 will hold the state of data on MISO until the falling edge of SCLK.

If the rising edge of the SCLK for the last data bit of the second write command occurs before the required delay (tSWW), then the first write command may not complete correctly. If the rising edge of SCLK for the last address bit of the read command occurs before the required delay (tSWR), the write command may not complete correctly. During a read operation SCLK should be delayed at least tSRAD a fter the last address data bit to ensure that the ADNS-6030 has time to prepare the requested data. The falling edge of SCLK for the first address bit of either the read or write command must be at least tSRR o r tSRW after the last SCLK rising edge of the last data bit of the previous read operation. Burst Mode Operation Burst mode is a special serial port operation mode that may be used to reduce the serial transaction time for a motion read. The speed improvement is achieved by continuous data clocking to or from multiple registers without the need to specify the register address, and by not requiring the normal delay period between data bytes. Burst mode is activated by reading the Motion_Burst register. The ADNS-6030 will respond with the contents of the Motion, Delta_X, Delta_Y, SQUAL, Shutter_Upper, Shutter_Lower and Maximum_Pixel registers in that order. The burst transaction can be terminated anywhere in the sequence after the Delta_X value by bringing the NCS pin high. After sending the register address, the micro-controller must wait tSRAD a nd then begin reading data. All data bits can be read with no delay between bytes by driving SCLK at the normal rate. The data are latched into the output buffer after the last address bit is received. After the burst transmission is complete, the micro-controller must raise the NCS line for at least tBEXIT t o terminate burst mode. The serial port is not available for use until it is reset with NCS, even for a second burst transmission. tSWW SCLK Address Data Address Data Write Operation Write Operation Figure 18.

Motion Burst Timing Notes on Power-up The ADNS-6030 does not perform an internal power up self-reset; the POWER_UP_RESET register must be written every time power is applied. The appropriate sequence is as follows: 1. Apply power 2. Drive NCS high, then low to reset the SPI port 3. Write 0x5a to register 0x3a 4. Wait for tWAKEUP 5. Write 0xFE to register 0x28 6. Read from registers 0x02, 0x03 and 0x04 (or read these same 3 bytes from burst motion register 0x42) one time regardless of the motion pin state. During power-up there will be a period of time after the power supply is high but before any clocks are available. The table below shows the state of the various pins during power-up and reset. Notes on Shutdown and Forced Rest The ADNS-6030 can be set in Rest mode through the Configuration_Bits register (0x11). This is to allow for further power savings in applications where the sensor does not need to operate all the time. The ADNS-6030 can be set in Shutdown mode by writing 0xe7 to register 0x3b. The SPI port should not be accessed when Shutdown mode is asserted, except the power-up command (writing 0x5a to register 0x3a). (Other ICs on the same SPI bus can be accessed, as long as the sensor’s NCS pin is not asserted.) The table below shows the state of various pins during shutdown. To deassert Shutdown mode: 1. Write 0x5a to register 0x3a 2. Wait for tWAKEUP 3. Write 0xFE to register 0x28 4. Any register settings must then be reloaded. *1 N CS pin must be held to 1 (high) if SPI bus is shared with other devices. It is recommended to hold to 1 (high) during Power Down unless powering up the Sensor. It must be held to 0 (low) if the sensor is to be re-powered up from shutdown (writing 0x5a to register 0x3a). *2 D epend on last state *3 S CLK is ignore if NCS is 1 (high). It is functional if NCS is 0 (low). *4 M OSI is ignore if NCS is 1 (high). If NCS is 0 (low), any command present on the MOSI pin will be ignored except power-up command (writing 0x5a to register 0x3a). Note: There are long wakeup times from shutdown and forced Rest. These features should not be used for power management during normal mouse motion. 19 Registers The ADNS-6030 registers are accessible via the serial port.

USAGE : Register 0x02 allows the user to determine if motion has occurred since the last time it was read. If the MOT bit is set, then the user should read registers 0x03 and 0x04 to get the accumulated motion. Read this register before reading the Delta_X and Delta_Y registers. Writing anything to this register clears the MOT and OVF bits, Delta_X and Delta_Y registers. The written data byte is not saved. Internal buffers can accumulate more than eight bits of motion for X or Y. If either one of the internal buffers overflows, then absolute path data is lost and the OVF bit is set. To clear theoverflow, write anything to this register. Check the OVR bit if more than 4" of motion is accumulated without reading it. If bit set, discard the motion as erroneous. Write anything to this register to clear the overflow condition. The PIXRDY bit will be set whenever a valid pixel data byte is available in the Pixel_Dump register. Check that this bit is set before reading from Pixel_Dump. To ensure that the Pixel_Grab pointer has beenreset to pixel 0,0 on the initial write to Pixel_Grab, check to see if PIXFIRST is set to high.

USAGE : SQUAL (Surface Quality) is a measure of the number of valid features visible by the sensor in the current frame. The maximum SQUAL register value is 127. Since small changes in the current frame can result in changes in SQUAL, variations in SQUAL when looking at a surface are expected. The graph below shows 800 sequentially acquired SQUAL values, while a sensor was moved slowly over white paper. SQUAL is nearly equal to zero, if there is no surface below the sensor. SQUAL is typically maximized when the navigation surface is at the optimum distance from the imaging lens (the nominal Z-height).

USAGE : This register is used to find the average pixel value. It reports the upper eight bits of a 17-bit counter, which sums all pixels in the current frame. It may be described as the full sum divided by 512. To find the average pixel value, use the following formula: Average Pixel = Register Value * 512/484 = Register Value * 1.058 The maximum register value is 241. The minimum is 0.

USAGE : For test purposes, the sensor will read out the contents of the pixel array, one pixel per frame. To start a pixel grab, write anything to this register to reset the pointer to pixel 0,0. Then read the PIXRDY bit in the Motion register. When the PIXRDY bit is set, there is valid data in this register to read out. After the data in this register is read, the pointer will automatically increment to the next pixel. Reading may continue indefinitely; once a complete frame’s worth of pixels has been read, PIXFIRST will be set to high to indicate the start of the first pixel and the address pointer will start at the beginning location again.

In contrast to most oxide-based single-mode VCSELs, this class of Agilent VCSELs remains within single mode operation over a wide range of output power. The ADNV-6330 has significantly lower power consumption than a LED. It is an excellent choice for optical navigation applications. Features · Advanced Technology VCSEL chip · Single Mode Lasing operation · Non-hermetic plastic package · 832-865 nm wavelength Notes: Because the can is not sealed, the protective kapton tape should not be removed until just prior to assembly into the ADNS-6120 or ADNS-6130-001 lens.

Suggested ADNV-6330 PCB Mounting Guide 35 1.5 Max PCB Thickness Comments: 1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are the stress ratings only and functional operation of the device at these or any other condition beyond those indicated for extended period of time may affect device reliability. 2. The maximum ratings do not reflect eye-safe operation. Eye safe operating conditions are listed in the power adjustment procedure section in the ADNS-6030 laser sensor datasheet. 3. The inherent design of this component causes it to be sensitive to electrostatic discharge. The ESD threshold is listed above. To prevent ESD-induced damage, take adequate ESD precautions when handling this product.

Appropriate binning resistor and register data values are used in the application circuit to achieve the target output power. Danger: When driven with current or temperature range greater than specified in the power adjustment procedure section, eye safety limits may be exceeded. The VCSEL should then be treated as a Class IIIb laser and as a potential eye hazard.
