Introduction

PCIE8XG4RD01 is SFF-8654 8x to SFF-8654 8x PCIe x8 Gen 4 (16 Gbps) ReDriver Board.

PCIE8XG4RD01 is designed with two Eight-Channel PCIe 4.0 Linear Redrivers to support PCIe Gen 4.0.

The Eight-Channel PCIe 4.0 Linear Redriver 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.

The linear redriver along with the passive channel as a whole get link trained for best transmit and receive equalization settings resulting in best electrical link and lowest possible latency. The linear redriver along with the passive channel as a whole get link trained for best transmit and receive equalization settings resulting in best lectrical link and lowest possible latency. Low channel-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 datapaths that provides high immunity to any supply
noise on the board.
