Product Description

The PI2DBS6212 is a 4 to 2 bi-directional differential channel multiplexer/demultiplexer switch supporting 6.5 Gbps applications. 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.
