Description
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 re-
enumeration 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.
