Switch multiplexes USB data, audio, microphone, and UART on a single connector port

Fairchild Semiconductor has introduced the FSA800, a 3:1 USB accessory switch that enables USB data, stereo and mono audio, microphone, and UART data to share a common connector port, and designed for high-speed USB 2.0 signaling. The FSA800 is suitable for mobile phone, PDA and MP3 player applications.

The Key features of the FSA800 are,

Built-in charger detection, simplifying design
Low on capacitance (7pf), allowing data to move swiftly along the signal path
Built-in termination resistors for audio pop reduction
28V of over-voltage tolerance on the VBUS pin to ensure robust protection against high voltage events
Negative swing capability so that audio signals can swing below ground, eliminating the need for AC coupling capacitors.

The FSA800 switches are ideal for USB port isolation, connector sharing and signal multiplexing, and also used to share or route USB ports and to isolate Flash memory / uDisk removable devices.
