ADNK-2623 Optical Mouse Designer’s Kit Design Guide Introduction Sensor 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 sensor technical information is contained in the ADNS-2620 Data Sheet. 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 disassembled 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. USB Controller Technical information on the Cypress enCoRe USB controller 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 Personality Board. 3-button, scroll wheel combi mouse. 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. System Requirements Lens PCs using Windows® 95/Windows® 98/ Windows® NT/ Windows® 2000 with PS/2 port and standard 3‑button USB mouse driver loaded. The lens technical information is contained in the HDNS2100 Data Sheet. The flange on the standard HDNS-2100 lens is for ESD protection. Operating (For PS/2 Mode) LED Assembly Clip Step 1: Turn off the PC. The information on the assembly clip is contained in the HDNS‑2200 Data Sheet. For more information, check out the Avago’s optical mouse sensor website. Functionality Step 2: Plug the mouse unit’s PS/2 connector into the PC’s 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 off when plugging or unplugging the evaluation mouse. Kit Components Refer to table on page 3. Avago Technologies in partnership with LED The LED technical information is contained in the HLMPED80-XX000 Data Sheet and Application Note 1282. Additional application notes regarding Eye Safety Requirements are also available on Avago’s website. Base Plate Feature —IGES File The IGES file on the floppy disc provides recommended base plate molding features to ensure optical alignment.
