VT5363

Single-chip USB/PS2 optical mouse

Features

■ Suitable for use with both LED and laser

(VCSEL) light sources

■ Single chip design with minimal support

circuitry

■ USB and PS2 operation

■ Single +5 V supply

■ No mechanical moving parts required

■ 800 cpi resolution (400 cpi selectable)

■ 9600 frames per second

■ Tracking at up to 40 ips

■ Up to 5 switch inputs and scroll wheel

■ Possible customizing for VID, PID and

descriptor string with external EEPROM

■ Proven, high volume package technology

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.

Applications

■ Optical USB/PS2 mouse for desktop PC,

workstation and laptop
