The FSUSB63 is a bi-directional, low-power, High-Speed (HS) USB 2.0 3:1 Multiplexer (MUX). It is optimized for switching among three high-speed (480Mbps) sources or any combination of high-speed and full-speed (12Mbps) USB sources, such as an application processor, to one USB 2.0 connector. The FSUSB63 has a break-before-make time to force reenumeration by the host when switching between different HS USB 2.0 controllers and thus requires minimal software changes. The FSUSB63 is compliant with the requirements of USB 2.0 and features extremely low on capacitance (CON). The wide bandwidth exceeds the requirement to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference.
