PCIe® 5.0 32-Gbps 4-channel linear redriver with integrated 1:2 demux

The SN75LVPE5412 is a four channel linear redriver with integrated demultiplexer

(demux). The low-power high-performance linear redriver is designed to

support PCIe 5.0 and other interfaces up to 32Gbps.

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 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 SN75LVPE5412 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.
