Overview
The SK7100 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 SK7100 works with most of popular force stick sensors with
tolerance up to +/- 20%. The SK7100 highly integrates oscillator, analog and
digital circuit to provide low cost and space saving solution. Only several low
tolerance external components are needed.
Typically, consuming 650uA in idle state, the SK7100 is ideal for
battery-operated systems.
Deploying CellMute technology to filter the wireless EMI noise
from cellular phones and wireless networks, the SK7100 can work quietly in
wireless environment.
The SK7100 partially implements the Lenovo TrackPoint®
extended command protocol and can work with Lenovo TrackPoint® device
drivers directly.
