The 10G-800G Multi-channel Multi-rate Ethernet/FiberChannel/FlexO Core (Epak800G_ZX) Core from Precise-ITC is a multi-rate Ethernet aggregator that supports tributaries from 800GE, to 1GE. It is our 3rd generation of Epak solution utilizing the 112G/s serdes and 56G/s serdes.
The supported ethernet protocols are 800GE, 400GE, 200GE, 100GE, 50GE, 40GE, 25GE, 10GE, 1GE, and 256GFC, 128GFC, 64GFC, 32GFC, 16GFC, 10GFC as well as FEC framing of FlexO-1/2/4-SR and OTU25/50-RS. It supports any legal combination of Ethernet/Fiberchannel/FlexO rate up to 800G. This Core supports up to a maximum of 8 ethernet channel and works most effective and efficient with latest 112G/s serdes. With Core clock frequency of 1.6GHz at 7nm or 5nm, this Core delivers smallest footprint among similar solution in the Ethernet/Fiberchannel/ FlexO SOC market.
The Core supports 800GE which uses a full 800GE MAC and a pair of “bonded” 2 x 400GE PCS. The 800GE takes advantage of 112G/s serdes and uses virtual logical lanes in a “bonded” 2 x 400GE PCS. This improves power efficiency in 800G operation. The 800GE is compliant to the Ethernet Technology Consortium Standard.
The north-bound interface from the multi-channel MAC provides a configurable system interface. The Multi-channel MAC manages the mapping between individual MACs and the assigned I/O or I/O group.
The southbound interface is mapped (at the PMA layer) to the on-chip SERDES. The core is responsible for channel alignment and FEC (where applicable).
