10G-1.6T Ethernet/FiberChannel/FlexO Core

The 10G-1.6T Multi-channel Multi-rate Ethernet/FiberChannel/FlexO Core (Epak1p6T_ZX)  from Precise-ITC is a multi-rate Ethernet aggregator that supports tributaries from 800GE, to 1GE. It is our 5th generation of Epak solution utilizing the 112G/s serdes and 56G/s serdes. The Epak 1p6T_ZX IP Core consists of Epak 1p6TMulti-channel and Multi-rate PCS and MAC Cores.

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 2x 800G (1.6T). This Core supports up to a maximum of 16 or 32 ethernet channels and works most effective and efficient with latest 112G/s serdes. With Core clock frequency of 800MHz to 1.6GHz at 7nm or 5nm, this Core delivers smallest footprint among similar solution in the Ethernet/Fiberchannel/FlexO SOC market.

800G Support

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.

Overview

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).
