SK7102 - FlexPoint™ PS/2 Pointing Stick Mouse Encoder
Overview
The SK7102 FlexPoint™ pointing stick mouse encoder is a cost-effective, space-saving and highly integrated IC that interfaces a force-stick sensor to PS/2 port.
The SK7102 works with most of popular force stick sensors with tolerance up to +/- 20%. The SK7102 highly integrates oscillator, analog and digital circuit. Only several low tolerance external components are needed.
Typically, consuming 0.89 mA, the SK7102 is ideal for battery-operated systems.
Deploying CellMute™ technology to filter the wireless EMI noise from cellular phones and wireless networks, the SK7102 can work quietly in wireless environment.
The SK7102 partially implements the Lenovo TrackPoint® extended command protocol and can work with Lenovo TrackPoint® device drivers directly.
