MTA41110

APPLICATION EXAMPLE
The MTA41110 controller can be configured as either
a mouse
or trackball controller.
Trackball systems
require the addition of the components labeled as
trackball only. These components allow support of a
drag lock switch and indicator. A pull-up resistor for the
drag lock switch must be included in trackball systems.
For a mouse, the DBTN input is simply connected to
VDD.
Three examples of motion encoders are shown in the
schematics (Document Number 41XXXEN).
Two
types of optical encoders and a mechanical type are
shown.
Since the MTA41110 employs an anti-jitter
algorithm, the “basic” style of optical encoder or the
mechanical encoder are both recommended for use
with the MTA41110. Use of the “improved” style of
optical encoder that employs comparators may only be
necessary in high noise environments.
All button switches should be of the momentary contact
type, including the drag lock switch.

Host System Device Drivers
The MTA41110 is compatible with standard IBM PS/2
device drivers.
Additionally,
host system software
device drivers for use with the MTA41110 are available
from third party vendors.
Contact your local sales
office for a list of vendors currently offering device
drivers that support the MTA41110.
