adnk-2623 optical mouse designers kit design guide introduction the adnk-2623 reference design mouse unit enables users to evaluate the performance of the optical tracking engine (sensor, lens, led assembly clip, led) over both a usb or ps/2 connection, using cypress encore usb controller. this kit also allows the user to understand the recommended mechanical assembly. (see figure 1.) the adnk-2623 comprises of the plastic case, printed circuit board (pcb), lens, buttons, and usb cable. (see figure 2.) unscrewing the one screw located at the base of the unit can open the adnk - 2623. it can be further dis - assembled by lifting and pulling the pcb out of the base plate. the lens is not permanently attached to the sensor and will drop out of the assembly. for more information, check out the avagos optical mouse sensor website. functionality 3-button, scroll wheel combi mouse. system requirements pcs using windows? 95/windows? 98/ windows? nt/ windows? 2000 with ps/2 port and standard 3 - button usb mouse driver loaded. operating (for ps/2 mode) step 1: turn of the pc. step 2: plug the mouse units ps/2 connector into the pcs ps/2 port. step 3: turn on the pc. all of the mouse buttons and scroll wheel will function exactly like a standard ps/2 mouse. operating (for usb mode) hot pluggable with usb port. the pc does not need to be powered of when plugging or unplugging the evalu - ation mouse. kit components refer to table on page 3. sensor the sensor technical information is contained in the ADNS-2620 data sheet. usb controller technical information on the cypress encore usb control - ler is contained in the cy7c63723 data sheet. the enclosed cypress lab cd-rom contains the development tools for the cy7c63723. these tools will allow the designer to make changes and recompile the source code. to perform in-circuit emulation for easier debugging of new code development, contact cypress to purchase the cy3654 development kit and the cy3654-p05 personal - ity board. programming support and programmer adaptors for the cypress cy7c63723-pc can be found through cypress (cy3649-xxxv + cy3083-dp48 + cy3083-07) or through most 3rd party programming companies. for further information on this product, please contact cypress semiconductor. lens the lens technical information is contained in the hdns- 2100 data sheet. the fange on the standard hdns-2100 lens is for esd protection. led assembly clip the information on the assembly clip is contained in the hdns - 2200 data sheet. led the led technical information is contained in the hlmp- ed80-xx000 data sheet and application note 1282. ad - ditional application notes regarding eye safety require - ments are also available on avagos website. base plate feature iges file the iges file on the floppy disc provides recom - mended base plate molding features to ensure optical alignment. reference design documentatio n gerber fle avago technologies in partnership with
