Wireless mouse IC Track-On-Glass Mouse Sensor

详情

General Description
The PixArt PAW***5EK-CJV1 is an optical sensor which is
optimized for infrared (IR) LED based wireless mouse
application. It has high accuracy navigation ability that
enables navigation virtually on any flat surface, including
the transparent glass. The low power architecture and
automatic power management make it suitable for
power-sensitive application such as a wireless mouse.
PAW***5EK-CJV1 is capable of high-speed motion
detection up to the velocity of *0 inches/sec and *0g on
non-glass surfaces, *0 inches/sec and acceleration of 5g
on glass surface. In addition, it has an on-chip oscillator
and a built-in programmable LED current driver. In order
to achieve the best tracking performance, it is
recommended to match the sensor with L***-LSI optical
lens.
