B­elow is the summary of the components contained in
the ADNK-3061 Designer’s Kit.
Sensor
The sensor technical information is contained in the
ADNS-3060 Data Sheet.
USB Controller
Technical information on the Cypress encore USB­ con-
troller is contained in the CY7C63743-PC Data Sheet.
The enclosed ADNK-3061 CD-ROM contains the devel-
opment tools for the CY7C63743-PC. 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. Programming support and pro-
grammer adaptors for the Cypress CY7C63743-PC can
be found through Cypress (CY3649-xxxV + CY3083-SC28
+ CY3083-08) or through most 3rd party programming
companies.
Lens
The lens technical information is contained in the ADNS-
2120 Data Sheet. The flange on the standard ADNS-2120
lens is for ESD protection.
LED Assembly Clip
The information on the assembly clip is contained in the
ADNS-2220 Data Sheet.
LED
The LED technical information is contained in the HLMP-
ED80-XX000 Data Sheet.

Base Plate Feature – IGES File
The IGES file on the CD-ROM provides recommended
base plate molding features to ensure optical alignment.
This includes PCB­ assembly diagrams like solder fixture
in assembly and exploded view, as well as solder plate.
See Appendix D for details.
Reference Design Documentation – Gerber File
The Gerber File presents detailed schematics used in
ADNK-3061 in PCB­ layout form. See Appendix C for more
details.
Overall circuit
A schematic of the overall circuit is shown in Appendix A
of this document. Appendix B­ lists the bill of materials.
Firmware Implementation
The firmware for this reference design is written in the
Cypress assembly language. The following files are
required to compile the mouse firmware 637xx.inc – the
CY7C63743-PC I/O registers definition.
adns-3060.asm – main mouse firmware
macros.inc – general macros used with this design
ps2.inc – PS/2 interface constants
usb.inc – USB­ interface constants
adns-3060_srom_12.inc – SROM firmware
At power up, the firmware examines the host interface
and automatically determines if the mouse is plugged
into a USB­ or a PS/2 host connection. After the interface
type has been determined, the host firmware configures
itself to operate on the detected interface.
USB Interface
All USB­ Human Interface Device (HID) class applications
follow the same USB­ start-up procedure. The procedure
is as follows:
1. Device Plug-in
When a USB­ device is first connected to the bus, it is
powered and running firmware, but communications on
the USB­ remain non-functional until the host has issued
a USB­ bus reset.
2. Bus Reset
The pull-up resistor on D– notifies the hub that a low
speed (1.5 Mbps) device has just been connected. The
host recognizes the presence of a new USB­ device and
initiates a bus reset to that device.
