PI3DBS16212

PCIe 4.0, 1-Lane (2-Channel), Differential 2:1 Mux/DeMux. 3.3V

Description

The PI3DBS16212 is a 4 to 2 differential channel multiplexer/demultiplexer switch. This solution can switch multiple signal types up to data rate of 20Gbps. Using a unique design technique, Diodes has been able to minimize the impedance of the switch such that the attenuation observed through the switch is minimal. The unique design technique also offers a layout targeted for USB3.0, USB3.1, 10GE, Thunderbolt 3, and SAS3.0 signals, which minimizes the channel to channel skew as well as channel to channel crosstalk as required by high-speed signals.
