DESCRIPTION
The PixiPoint
TM
Z mouse encoder
is a cost-effective, high-
functionality IC designed to
interface the CTS 106, 108 and
109 sensors to the PS/2 port. Ideal
for laptop/palmtop use, the low
power PixiPoint
TM
Z offers an
advanced algorithm for enhanced
motion control. The IC also
enables click, double-click,
MouseWheel action and slow drag
without the need for special
drivers. The IC provides an extra
port for hot-plug connection of an
external pointing device, including
those with built-in Mousewheel.
Both the embedded sensor and
the external device can be
operated concurrently.
The PixiPoint
TM
Z utilizes a special
signal conditioning circuit (US and
International patent pending) which
enables a low cost, simple and real
estate-saving implementation. Just
a few low tolerance external
components are needed.
The IC implements typically
consumes less than 3mA, making it
suitable for use in battery-operated
systems.
PS/2 communication is
bidirectional at 10 kbps. The IC, a
CMOS device operating at 4 MHz,
is compatible with both the IBM
and Microsoft two-button and the
Logitech three-button mouse
protocols. It implements all
commands from and to the system,
as defined in the IBM PS/2 Mouse
Communication Protocol. Custom
versions are also available to suit a
range of applications.
