Description
The ADNS-2001 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 mathematic-
ally determining the direction and
magnitude of movement. The
sensor is mounted in a plastic
optical package and designed to be
used with the HDNS-2100 (Lens),
HDNS-2200 (LED Assembly Clip)
and HLMP-ED80 (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 ADNS-2001
offers a PS/2 or quadrature output
mode for interface flexibility.
Resolution is specified as 400 cpi
at rates of motion up to 16 inches
per second.

Theory of Operation
The ADNS-2001 is based on
Optical Navigation Technology. It
contains an Image Acquisition
System (IAS), Digital Signal Pro-
cessor (DSP), and a mode select-
able PS/2 or quadrature output
converter. The IAS acquires im-
ages of microscopic surface im-
ages via the lens and illumination

system provided by the HDNS-
2100, HDNS-2200, and the
HLMP-ED80. These images are
further processed by the DSP to
determine direction and distance
of motion. The DSP generates a
stream of delta x and delta y rela-
tive displacement values which
are then communicated to the
output converter. This converter
provides a PS/2 3-button output,
replacing existing mouse
microcontrollers, or two channel
quadrature output, for direct
interface to existing mouse
microcontrollers.
While the part can be run at 24
MHz in quadrature mode, 18 MHz
is recommended for PS/2 mode.

Typical USB Application using
Quadrature Output
18 or 24 MHz Operation
Notes:
1. Due to the Cypress implementation of USB suspend mode support, the NRESET pin of the ADNS-2001 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 has received a bus reset from the USB port.
The unconfigured input port pins present a 16 KΩ pullup to VCC. If a cap is used on NRESET (pin 15), this pullup will result in the ADNS-2001
seeing a high on the MODE pin and powering up in the PS/2 mode.
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
ADNS-2001 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.

Host Sending Data Timing Diagram
Notes:
1. The mouse checks the DATA line. If the line is low, the system has data to transmit. The DATA line is set inactive when the start bit (always 0) is
placed on the DATA line.
2. The mouse samples the DATA line for each bit while the CLK line is high. Data must be stable within 1 microsecond after the rising edge of the
CLK line.
3. The mouse checks for a high stop bit after the 10th CLK. If the DATA line is low, the mouse continues to clock until the DATA line becomes high,
then clocks the line-control bit, and at the next opportunity sends a Resend command to the system.
4. The mouse pulls the DATA line low, producing the line-control bit.
5. The host can pull the CLK line low, inhibiting the mouse.

Quadrature Output Mode Waveform
@ 24 MHz
The 2 channel quadrature outputs
are 5 V CMOS outputs. The Delta
X count is used to generate the
XA and XB quadrature signals.
The Delta Y count is used to gen-
erate the YA and YB quadrature
signals. Delta X, Y counts are in
the range of +7 to –7 counts of
motion and new Delta X, Y values
are generated at a rate of 2000
Hz. The quadrature signals can
change at a maximum rate of
16.7 kHz.
Example: Quadrature Output Waveform (+X motion).
