ADNK-2623

Optical Mouse Designer’s 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 Avago’s optical

mouse sensor website.

Functionality

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 flange 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 Avago’s website.
