7 Appendix 4: 1G Ethernet BASE-T and BASE-X Using Transceiver

The PolarFire FPGA family includes multiple embedded low-power, performance-optimized transceivers. Each transceiver has both the Physical Medium Attachment (PMA), the protocol Physical Coding Sub-Layer (PCS) logic, and the interfaces to the FPGA fabric. The transceiver has a multi-lane architecture with each lane natively supporting serial data transmission rates from 250 Mbps to 12.7 Gbps. For more information, see PolarFire FPGA and PolarFire SoC FPGA Transceiver User Guide.

This section describes how 1G Ethernet BASE-T and BASE-X designs are implemented in PolarFire FPGAs using the transceivers.
