Product Description

The PI2USB3212 is a 1 to 2 bi-directional differential channel multiplexer/demultiplexer switch supporting 5.0 Gbps applications, such as USB 3.2 Gen 1. Due to its low bit-to-bit skew, high channel-to-channel noise isolation and high bandwidth, this product is ideal for switching two sources to a single receiver, or alternatively, one source to two receivers.
