Versal ACAP devices have a integrated 600G Interlaken (ILKN) core with FEC supports channelized interfaces operating up to 600 Gb/s with built-in flow control. Each 600G Interlaken core can be configured as maximum 24 lanes with 12.5G and 28.21G transceivers or minimum 12 lanes with 56.42 transceivers. The flexible AXI4-Stream user interface is configurable in width from 2048b to 512b. Pairs of lanes share 100G RS(544, 514) FEC and can support FEC-only mode.
