Description
The VT5363 optical tracking sensor is a complete
solid state tracking engine with no moving parts.
This single chip optical mouse sensor provides
excellent control and precision and works on a
wide range of surfaces.
The VT5363 supports 2, 3 or 5 button mouse
designs with a mechanical scroll wheel encoder. It
contains a dual USB/PS2 interface with automatic
interface selection and may be powered directly
from the USB or PS2 port. A single 6MHz
resonator provides all the clock requirements and
a minimum of additional passive components are
required.
An external EEPROM may be used to implement
customer specific USB configurations (PID, VID
and descriptor string).
The VT5363 sensor operates over a wide range
of illuminant wavelengths. For devices operating
at approximately 850nm (IR LED or VCSEL), the
on-die automatic exposure controller (AEC)
compensates for the change in sensitivity
compared to 640nm (red LED). Motion
performance can be improved by increasing the
current supplied to the navigation LED.
A specifically designed optical system with
integrated light guide and lens is available. This
has been optimized for low cost, space saving
and ease of mouse manufacture. No kapton tape
is required in the assembly process.
