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.
