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
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
While the part can be run at 24
MHz in quadrature mode, 18 MHz
is recommended for PS/2 mode.
