Pericom Semiconductor PI3DBS12x12A are differential channel multiplexer/demultiplexer switches. They can switch multiple signal types up to a data rate of 12Gbps. The impedance of the switches have been minimized using a unique design technique. The attenuation observed through the switches are minimal. They also offers a layout targeted for Thunderbolt & SAS 3.0 signals. This minimizes the channel to channel skew and channel to channel crosstalk as required by high speed signals.
