Description
Pericom Semiconductor’s PI3USB302-A is a 2-differential chan-
nel bi-directional multiplexer/demultiplexer switch. Due to its
low bit-to-bit skew, high channel-to-channel noise isolation and
bandwidth, this product is ideal for USB 3.0 signal switching at
5.0 Gbps.
Application
Routing USB 3.0 SuperSpeed signals
