4 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 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. figure 3. recommended pcb mechanical cutouts and spacing 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.

7 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 adns- 6030 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 v dd to 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.
8 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 v dd value is no greater than 300mv above its value at the time of adjustment. 4. no allowance for optical power meter accuracy is assumed. figure 6. single fault detection and eye-safety feature block diagram laser_nen xy_laser gnd adns-6030 laser driver v dd vcsel microcontroller serial port voltage sense current set v dd fault control block disabling the laser laser_nen is connected to the gate of a p-channel mosfet transistor which when on connects v dd to the laser. in normal operation, laser_nen is low. in the case of a fault condition (ground or v dd at xy_laser), laser_nen goes high to turn the transistor off and disconnect v dd from 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 v dd , this test will fail and will be reported as a fault.

16 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. mode response time (nominal) downshift time (nominal) rest 1 33ms 237ms rest 2 164ms 8.4s rest 3 840ms 504s 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 non- use 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 burst- mode transaction is complete to terminate burst-mode. the port is not available for further use until burst-mode is terminated. 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. motion pin timing the motion pin is a level- sensitive 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.
17 figure 17. read operation figure 16. write operation read operation a read operation, defined as data going from the adns- 6030 to the micro-controller, is always initiated by the micro- controller 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 adns- 6030 over miso. the sensor outputs miso bits on falling edges of sclk and samples mosi bits on every rising edge of sclk. figure 15. mosi setup and hold time a 6 a 5 a 2 a 3 a 4 a 0 a 1 d 7 d 4 d 5 d 6 d 0 d 1 d 2 d 3 15 7 8 9 10 11 12 13 14 16 2 3 4 5 6 1 sclk mosi mosi driven by micro 1 1 1 a 6 2 ncs miso sclk mosi t setup , mosi hold,mosi t 1 2 3 4 5 6 7 8 sclk cycle # sclk mosi 0 a 6 a 5 a 4 a 3 a 2 a 1 a 0 9 10 11 12 13 14 15 16 miso d 6 d 5 d 4 d 3 d 2 d 1 d 0 d 7 ncs t srad delay sclk miso d 0 t t dly-miso hold-miso write operation write operation, defined as data going from the micro- controller 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. figure 14. miso delay and hold time 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 adns- 6030 will hold the state of data on miso until the falling edge of sclk.

19 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 sensors 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 t wakeup 3. write 0xfe to register 0x28 4. any register settings must then be reloaded. * 1 ncs 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 depend on last state * 3 sclk is ignore if ncs is 1 (high). it is functional if ncs is 0 (low). * 4 mosi 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. 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 t wakeup 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. figure 21. motion burst timing motion_burst register address read first byte first read operation read second byte sclk t srad read third byte
