The SN75LVPE5421 is a four channel linear redriver with integrated multiplexer (mux). The low-power high-performance linear redriver is designed to support PCIe 5.0 and other interfaces up to 32Gbps.
The SN75LVPE5421 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 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 allows the device to become almost a passive element in the link. The devices has internal linear voltage regulator to provide clean power supply for high speed data paths that provides high immunity to any supply noise on the board.
The SN75LVPE5421 implements high speed testing during production for reliable high volume manufacturing. The device also has low AC and DC gain variation providing consistent equalization in high volume platform deployment.
