Description
The FSA806 is a 3:1 USB accessory switch that enables
USB data, stereo and mono audio, and UART data to
share a common connector port. Two ports are
designed for high-speed USB 2.0 signaling, while also
capable of full speed USB and UART communication.
The architecture is designed to allow audio signals to
swing below ground so a common USB and headphone
jack can be used for personal media players and
portable peripheral devices.
The FSA806 meets both USB Rev. 2.0 and micro-USB
specifications.
