DESCRIPTION/ORDERING INFORMATION
The TS2PCIE2212 can be used to muxltiplex/demultiplex two PCI Express™ lanes, each representing
differential pairs of receive (RX) and transmit (TX) signals. The switch operates at the PCI Express bandwidth
standard of 2.5-Gbps signal-processing speed. The device is composed of two banks, with each bank
accommodating two sources (source A and source B) and two destinations (destination A and destination B).
When a logic-level low is applied to the control (CTRL) pin, source A is connected to destination A and source B
is connected to destination B. When a logic-level high is applied to CTRL, source A is connected to destination
B, while source B and destination A are open.
