The E-pak SOC Core from Precise-ITC is a multi-rate Ethernet aggregator that supports tributaries from 800GE, to 1GE. E-pak 1.6T is our 5th generation of E-pak solution utilizing the 112G/s serdes and 56G/s serdes. The SOC consists of Epak 1p6T MC PCS and Epak 1p6T MC MAC Core.
The supported ethernet protocols are 800GE, 400GE, 200GE, 100GE, 50GE, 40GE, 25GE, 10GE, 1GE, 10GFC, 16GFC, 32GFC, 64GFC, 128GFC, 256GFC as well as FEC framing of FlexO-1/2/4-SR. It supports any legal combination of Ethernet /Fiberchannel/FlexO rate up to 2x800G (1.6T). This Core supports up to a maximum of 16 or 32 ethernet channel and works most effective and efficient with latest 112G/s serdes. With Core clock frequency of 670MHz to 1.6GHz at 7nm or 5nm, this Core delivers smallest footprint among similar solution in the Ethernet/Fiberchannel/FlexOSOC 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).
