9 pcb layout considerations: 1. the dgnd and agnd paths must be layout as far as possible and connected together at the usb ground point with star topology. ensure large grounding plane on the pcb layout for better performance on esd and eftb. 2. all caps must be as close to vdd5, refa, refb & +vcsel sensor pins as possible and ground at the dgnd and agnd plane that connected to usb gnd, with trace length less than 5mm. 3. 1.5k ? pullup resistor (r1) should be 1% tolerance and connected to refb pin with shortest possible trace length. 4. ceramic non-polarity caps and tantalum polarity caps are recommended. 5. caps should have less than 5nh of self inductance. 6. caps connected to vdd5 must have less than 0.2 ? esr. 7. refc pin requires an open ended trace of min 50 mm lengths within dgnd plane for eftb performance im- provement. refer to system design recommendations application note. 8. do not use jumper on ground plane, d+ and d- paths. 9. data lines (d+ and d-) should be as far as possible from resonator. pcb assembly considerations 1. insert the sensor package and all other electrical components into the application pcb. to maintain the z alignment of sensor package, the sensor reference plane can be sit directly on the pcb. 2. this sensor package is only qualifi ed for wave-solder process. 3. wave solder the entire assembly in a non-wash solder process utilizing solder fi xture. the solder fi xture is needed to protect the sensor during the solder process shielding the optical aperture from direct solder contact. 4. place the lens onto the base plate. care must be taken to avoid contamination and scratches on the optical surfaces. 5. hold the pcb vertically and remove the kapton tape attached to the respective aperture of sensor and vcsel. during the removal process of kapton tape, care must be taken to prevent contaminants from entering through the apertures. do not place the pcb facing upwards during the entire mouse assembly process. 6. place the pcb over the lens onto base plate. the sensor package should be self-aligned and locked to the lens by the lens alignment guide posts. the optical center reference for the pcb is set by base plate and lens. note that the pcb movement due to button presses must be minimized to maintain good optical alignment. 7. optional: the lens can be permanently locked to the sensor package by melting the lens guide posts over the sensor with heat staking process. 8. then, install the mouse top case. there must be feature in the top case (or other area) to press down onto the sensor or pcb assembly to ensure the sensor and lens are interlocked to 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. assumption: base plate construction as per the avago supplied 3d model fi le when use with adns-6180- 001 trim lens or adns-6180-002 wide trim lens. the lens fl ange can be sealed (i.e. glued) to the base plate. note that the lens material is polycarbonate and therefore, cya- noacrylate based adhesives or other adhesives that may damage the lens should not be used. typical distance (mm) adns-6180-001 trim lens adns-6180-002 wide trim lens creepage 5.5 17.5 clearance 1.8 1.8 regulatory requirements ? passes fcc b and worldwide analogous emission limits when assembled into a mouse with unshielded cable and following avago technologies recommendations. ? passes en 61000-4-4/iec 801-4 eft tests when assembled into a mouse with shielded cable and following avago technologies recommendations. ? passes iec-61000-4-2 electrostatic discharge immunity test (esd) and provides suffi cient esd creepage/ clearance distance to withstand up to 12 kv discharge when assembled into a mouse with adns-6180-001 trim lens and up to 15 kv discharge when assembled into a mouse with adns-6180-002 wide trim lens. ? passes iec/en 60825-1 class-1 eye safety when adns- 7700 is driving the laser using adns-6180-001 or adns-6180-002 lens with recommended operating conditions.

17 one-time-programmable (otp) memory the on chip otp memory allows device confi guration fl ex- ibility to override the default setting of adns-7700 sensors without any external software driver. once the otp op- eration is enabled, all otp registers must be programmed accordingly as the default values of un-program otp reg- isters are always zero when l2_use_otp register setting is not zero value. tips: otp write to the otp register can be skipped if the setting is zero value (0x00) in order to save the otp programming time. otp address space is from 0x80 to 0xfe. otp can be pro- grammed via usb interface using set vendor test and get vendor test commands. figure 16. otp byte write flow chart otp byte write operation otp write operation fl ow chart is shown in figure 16. 1. set otp enable bit in otp_config register, 0x4c: otp_en = 1. 2. write the otp register address byte to otp_addr register, 0x4d. 3. write the otp data byte to otp_data register, 0x4e. 4. set write enable bit in otp_ctrl register, 0x4f to enable write command to otp: wr = 1. 5. read the write enable bit status in otp_ctrl register, 0x4f. if wr = 1, repeat reading the bit status until it is clear. 6. read the write status bit in otp_ctrlstat register, 0x50. a. if wr_ok = 1, otp write operation is completed. repeat step 2 for more otp byte write operations. b. if wr_ok = 0, repeat step 4. 7. if step 6b is repeated up to 10 times, otp write operation is failed and the chip is confi rmed as defective unit. write otp addr byte bit = 0? start write otp data byte write otp enable bit write otp program bit read otp program bit no read otp status bit bit = 1? no repeat = 10? no yes otp write fail yes more bytes? yes yes repeat = 1 repeat = repeat + 1 bad chip otp write pass done no 0x4c: otp_config [0] = 1 0x4d: otp_addr [7:0] 0x4e: otp_data [7:0] 0x4f: otp_ctrl [0] = 1 0x50: otp_ctrlstat [0] 0x4f: otp_ctrl [0]

20 buttons and tilt wheel the minimum time between button presses is t dbb . buttons, b1 through b5 and tilt wheel are connected to a schmidt trigger input with 100 ? a current sources pulling up to +5.0v during run, rest and usb suspend modes. the tilt wheel feature can be enabled or disabled via otp register. all designers and manufacturers of fi nal product with tilt wheel enabled must assure that they have all necessary intellectual property rights. debounce algorithm ?? button inputs b1, b2, b3, b4, b5, tw1 and tw2 are sampled every 2ms. ?? three consecutive low values create a button press event. ?? three consecutive high values create a button release event. z-wheel adns-7700 is designed to be used with mechanical z- wheel for vertical scrolling. the z-wheel reporting format which determines the vertical scroll resolution is z/2 as most of the commonly available mechanical z-wheel en- coders come with lower sensitivity. on-the-fly (otf) resolution mode the adns-7700-hamy, adns-7700-hcmy and adns- 7700-hmmy sensors are enhanced with programmable on-the-fly (otf) resolution mode, which user is able to switch resolution setting anytime with otf button click. otf mode can be activated from otp register 0xc1 by writing either 01 or 10 to otf [1:0]. when otf [1:0] = 00 or 11, the resolution setting is fi xed as per cpi_set0 reg- ister confi guration. refer to table 4 on the confi gurable options. every otf button click triggers the change of resolution setting from current state to next state. the otf state machine as shown in figure 19 implements in the se- quence of s0: cpi_set0, s1: cpi_set1 and s2: cpi_set2 in a cycle. the default state upon adns-7700 sensor power up is always at s0. for adns-7700-hamy sensor, the otf state can be dis- played with led indication via led0, led1 and led2 pins. led0, led1 and led2 are active high output and can be connected to the base of a npn bi-polar junction transis- tor (bjt) which when on connects vdd to the led. the button click for otf mode in ADNS-7700-HMMY re- quires long press. the long press timing is confi gurable via longpress register, 0xc6 with default timing of 0.256s. figure 19. otf resolution mode state machine s0 cpi_set0 s1 cpi_set1 s2 cpi_set2 otf button 1 st pressed otf button 2 nd pressed otf button 3 rd pressed table 3. otf led indication status for adns-7700-hamy state sequence current state status previous current led0 led1 led2 s2 s0 high low low s0 s1 low high low s1 s2 low low high keymap (km) keymap mode enables b4, b5, tw1 or tw2 button to be assigned as keyboard shortcut key. thus, the sensor can be customized to implement standard microsoft keyboard shortcut keys or special shortcut keys used in diff erent ap- plications, eg. offi ce, cad, pc games, etc. table 3 shows the confi guration of km1 and km2 pins in keymap mode. km [1:0] bits in devconfig register, 0xc1 must comple- ment to each other in order to enable keymap modes. km1 will be implemented as per codea setting while km2 will be implemented as per codeb setting. codea and code b allow confi guration of two and above keys combi- nation (eg. alt+tab, alt+ctrl+del). codea = codea_key1 register, 0xc2 + codea_key2 reg- ister, 0xc4 codeb = codeb_key1 register, 0xc3 + codeb_key2 reg- ister, 0xc5 codea_key1 and codeb_key1 registers consist of 8 pre- defi ned keyboard keys: microsoft logo gui, alt, shift and ctrl keys located at left and right sides. codea_key2 and codeb_key2 registers can be programmed with a key- board key scan code available from windows platform design notes on keyboard scan code specifi cation, which can be downloaded from: http://www.microsoft.com/whdc/archive/scancode.mspx
