FSA800UMX

FSA800 — USB2.0 High-Speed (480Mbps), UART, and Audio Switch with Negative Signal Capability Features Description ƒ Negative-Swing-Capable Audio Channel The FSA800 is a 3:1 USB accessory switch that enables USB data, stereo and mono audio, microphone, 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 so a common USB and headphone jack can be used for personal media players and portable peripheral devices. Built-in Termination Resistors for Audio Pop Reduction FSA800 detects wall chargers through a dedicated pin that provides the baseband with charger detection. Simple Switch Control Using Three Select Pins The FSA800 meets both USB Rev. 2.0 and micro-USB specifications. ƒ ƒ ƒ ƒ ƒ 3:1 Switch Handles: Audio Headsets UART High- and Low-Speed USB Data USB Charger Detection and Indication - 28V Over-Voltage Tolerance on VBUS Applications IMPORTANT NOTE: ƒ For additional performance information, please contact analogswitch@fairchildsemi.com.
