Overview
The FSUSB63UMX, produced by onsemi, is a bi-directional, low-power, High-Speed (HS) USB 2.0 3:1 Multiplexer (MUX). It is designed to switch among three high-speed (480Mbps) or any combination of high-speed and full-speed (12Mbps) USB sources to one USB 2.0 connector. This component is particularly useful in applications requiring minimal software changes when switching between different HS USB 2.0 controllers, thanks to its break-before-make time that forces reenumeration by the host.
