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.
