SN75LVPE5412 Four-Channel Linear Redriver

Texas Instruments SN75LVPE5412 Four-Channel Linear Redriver is a low-power, high-performance linear redriver designed to support PCIe 5.0 and other interfaces up to 32Gbps. The device comes with an integrated demultiplexer (demux). The SN75LVPE5412 receivers deploy continuous-time linear equalizers (CTLE) to provide a high-frequency boost. The equalizer can open an input eye that is completely closed due to inter-symbol interference (ISI) induced by an interconnect medium, such as PCB traces and cables. During PCIe link training, the linear redriver and the passive channel between a Root Complex (RC) and Endpoint (EP) get trained for excellent transmit and receive equalization settings resulting in a tremendous electrical link. Low channel-to-channel cross-talk, low additive jitter, and incredible return loss allow the device to become almost a passive element in the link. The device has an internal linear voltage regulator to provide a clean power supply for high-speed data paths that offers high immunity to any supply noise on the board.
