The 600G channelized multirate Ethernet subsystem (DCMAC) provides up to 600G of Ethernet bandwidth that can be configured for various rates including 1x400GE, 3x200GE, and 6x100GE. The DCMAC handles all protocol-related functions of an Ethernet MAC, PCS, and FEC, including handshaking, synchronizing, and error checking. It also provides a segmented AXI4-Stream interface for packet data and an AXI4-Lite interface for statistics and management.

The DCMAC can be configured to include forward error correction (FEC) capability, supporting Clause 91 RS(528, 514) KR4 FEC, Clause 91 RS(544, 514) KP4 FEC, Clause 119 RS(544, 514) KP4 FEC, and Clause 134 RS(544, 514) FEC.

The DCMAC flexible interface (FLEXIF) supports several operating modes including OTN, FlexE, and PCS modes.
