PI3DBS16413 PCIe Gen 4 Mux/DeMux Switch Diodes Incorporated PI3DBS16413 PCIe Gen 4 Mux / DeMux Switch is a multiplexer/demultiplexer that switches multiple signal types up to a data rate of 20Gbps. This 12-to-4 differential channel Mux switch uses a unique design technique to reduce impedance. This design technique also offers a layout targeted for USB 3.0, USB 3.1, 10GE, Thunderbolt 3, and SAS 3.0 signals to minimize the channel-to-channel skew and channel-to-channel crosstalk. Diodes Incorporated switches are ideal for routing high-speed differential signals such as USB 3.1 Gen 2, SAS 3, PCIe 4, and TB3.
