sensor is mounted in a plastic
optical package and designed to
be used with the HDNS-2100
(Lens), HDNS-2200 (LED Assembly

(High Light Output 639 nm LED),
providing a complete and compact
tracking engine. This optical
tracking engine has no moving
parts and requires
no precision optical alignment
enabling high volume system
assembly. The HDNS-2000 offers a
PS/2 or quadrature output mode

motion up to 12 inches per second.
Description
The HDNS-2000 is a low-cost
reflective optical sensor that
provides a non-mechanical
tracking engine for implementing
a computer mouse.
It is based on optical navigation
technology which measures
changes in position by optically
acquiring sequential surface
images (frames) and mathemat-
ically determining the direction
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component
to prevent damage and/or degradation which may be induced by ESD.

Theory of Operation
The HDNS-2000 is based on
Optical Navigation Technology.
It contains an Image Acquisition
System (IAS), Digital Signal
Processor (DSP), and a mode
selectable PS/2 or quadrature
output converter. The IAS
acquires images of microscopic
surface images via the lens and
illumination system provided by
the HDNS-2100, HDNS-2200 and
the HLMP-ED80-XXXXX. These
images are further processed by
the DSP to determine direction
and distance of motion. The DSP
generates a stream of x and y
relative displacement values
which are then communicated to
the output converter. This con-
verter provides a PS/2 3-Button
output, replacing existing mouse
microcontrollers, or two channel
quadrature output, for direct
interface to existing mouse
microcontrollers.

NOTES:
1) DUE TO THE CYPRESS IMPLEMENTATION OF USB SUSPEND
MODE SUPPORT, THE NRESET PIN OF THE HDNS-2000 MUST BE
RESET USING A LINE FROM THE CYPRESS CHIP. THE REASON
FOR THIS IS THAT THE CYPRESS CHIP DOES NOT CONFIGURE THE
PORT INPUT PINS UNTIL AFTER IT HASRECEIVED A BUS RESET
FROM THE USB PORT. THE UNCONFIGURED INPUT PORT PINS
PRESENT A 16 K
Ω
PULLUP TO V
CC
. IF A CAP IS USED ON NRESET
(PIN 15), THIS PULLUP WILL RESULT IN THE HDNS-2000 SEEING
A HIGH ON THE MODE PIN AND POWERING UP IN THE PS/2.
2. THE QUADRATURE INPUT PINS OF THE CYPRESS PART MUST BE
PROGRAMMED TO BE HI-Z, INSTEAD OF THE NORMAL CURRENT
PULLDOWNS. THIS ENSURES THAT THE HDNS-2000 WILL BE ABLE
TO PULL THE QUADRATURE LINES HIGH OVER ALL CONDITIONS
OF VOLTAGE AND TEMPERATURE.
3. 0.1 µF BETWEEN PINS 7 AND 8 MUST BE CERAMIC AND MUST BE
TRACE LENGTHS LESS THAN 5 mm.
