Description
Pericom Semiconductor’s PI3USB302-A is a 2-differential channel 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
