The Versal adaptive SoC Multirate Ethernet MAC (MRMAC) provides high-performance, low latency Ethernet ports supporting a wide range of customization and statistics gathering. The MRMAC supports the following forward error corrections (FECs) defined and required by IEEE standards: Clause 91 RS(528, 514) KR4 FEC for 25/50/100GE NRZ support, Clause 91 RS(544, 514) KP4 FEC for 50/100GE PAM4 support, and Clause 74 FEC, for 10/25/40/50GE low-latency support. The MRMAC has a rich set of bypass modes to enable access to FEC-only mode (for custom protocols) and FEC+PCS (for protocol testers). For more information, see the Versal Devices Integrated 100G Multirate Ethernet MAC (MRMAC) LogiCORE IP Product Guide (PG314).

Note: MRMAC availability is device specific.
