Introduction

The VT5363 sensor is a single-chip solid state optical tracking engine with no moving parts.

It allows the creation of a high performance, fully featured mouse with the minimum of

external components. The device provides excellent navigation control and precision and

works on a wide range of surfaces.

VT5363 incorporates features that simplify product design and reduce time to market. By

minimising the number of external components, the mouse manufacturer has flexibility for

layout and product design.

ST has worked with optical component suppliers to produce a single piece light guide with

integrated lens, and recommendations for a compatible LED. Details of the optics and LED

are included in this datasheet.The main functional blocks of the VT5363 are shown in

Figure 1.
