Description
The FSA805 is a 3:1 USB accessory switch that
enables USB data, stereo/mono audio, and UART data
to share a common connector port. It is designed for
high-speed USB 2.0 signaling. The architecture is
designed to allow audio signals to swing below ground
(to -0.8V) so a common USB and headphone jack can
be used for personal media players and portable
peripheral devices.
The FSA805 meets both USB Rev. 2.0 and micro-USB
specifications.
