SN75LVPE5412 PCIe® 5.0 4-Channel Linear Redriver

Texas Instruments' SN75LVPE5412 is a four-channel linear redriver with an integrated demultiplexer (demux). The low-power high-performance linear redriver is designed to support PCIe 5.0 and other interfaces up to 32 Gbps. 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 along with the passive channel in between a root complex (RC) and endpoint (EP) as a whole get trained for the best transmit and receive equalization settings resulting in the best electrical link.

Low channel-to-channel cross-talk, low additive jitter, and excellent return loss allow the device to become an almost passive element in the link. The device has an internal linear voltage regulator that provides a clean power supply for high-speed data paths providing high immunity to supply noise on the board. The SN75LVPE5412 implements high-speed testing during production for reliable high-volume manufacturing. The device has low AC and DC gain variation providing consistent equalization in high-volume platform deployment.
