FSA110 — Audio and Wired-OR USB2.0 Hi-Speed Switch with Negative Signal Capability and Built-in Termination www.DataSheet4U.com November 2009 FSA110 — Audio and Wired-OR USB2.0 Hi-Speed (480Mbps) Switch with Negative Signal Capability and Built-in Termination Features ƒ ƒ ƒ ƒ ƒ ƒ ƒ 6pF Typical Switch Off Capacitance for HS USB 2.5Ω Typical On Resistance for Audio Signaling Negative-Swing-Capable Audio Channel Automatic USB Detection Available Power-Off Protection on the D+/R, D-/L Ports Flow-Through Pin Out Eliminates PCB Vias Built-In Termination on Unselected Audio Paths Inhibits Audio Pop Description The FSA110 is a Double-Pole, Single Throw (DPST) switch that combines a low-distortion audio path with low off capacitance for USB applications. This configuration is ideal for wired-OR configurations, enabling shared USB2.0 Hi-Speed (HS) and audio on a single connector. 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 FSA110 is configured for default USB transfer, which gives the user control of when the audio path is enabled. The audio path defaults to audio mute and is enabled with /OE. The FSA110 includes a power-off feature on the common port when VCC=0V to guarantee signal isolation.
