Core10GBaseKR_PHY

Core10GBaseKR_PHY provides the physical layer for Ethernet backplane links between an XGMII-based Media Access Control and a transceiver operating in Physical Medium Attachment mode. It exists for designs that need a standards-aligned path from MAC data to serial backplane signaling without building the PHY layer from discrete logic. The core combines coding, link establishment, and receive clock compensation so the FPGA can bring up robust board-to-board Ethernet channels with less custom development. It is suited to systems that must negotiate link capability, train the channel, and maintain reliable traffic transfer across backplane conditions. By integrating the protocol-specific PHY functions in hardware, the core reduces software burden and simplifies system partitioning around the transceiver and MAC. It also supports optional forward error correction, which helps extend usability across more challenging backplane channels. Control and status access lets software supervise link bring-up while the data path remains in dedicated hardware. The core is especially valuable in communications and embedded compute platforms that need interoperable Ethernet backplane connectivity using PolarFire® FPGA and PolarFire SoC FPGA transceivers.
