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). 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.
