DESCRIPTION/ ORDERING INFORMATION
The TS2PCIE412 is a 4-channel PCIe 2:1 multiplexer/demultiplexer switch that can be used to route one PCIe
data lane between two possible destinations or two PCIe data lanes to one destination. Each channel consists of
differential pairs of receive (RX) and transmit (TX) signals and operates at a signal-processing bandwidth speed,
which supports the PCIe standard of 2.5 Gbps. The device is controlled with one select input (SEL) pin, where
SEL controls the data path of the multiplexer/demultiplexer and can be connected to any GPIO in the system.
The unselected channel is set in a high-impedance state.
