800G Ethernet IP for AI Application

Overview

The Alphawave IP OmegaCORE 800G_AX is a cutting-edge solution with the latency, power, and area highly optimized for artificial intelligence applications. It supports the Physical Coding Sublayer (PCS) for 64B/66B, type 800GBASE-R function based on the IEEE 802.3bs/cd, Forward Error Correction (FEC), and Media Access Control (MAC) layer function. It supports a single-channel of 800GE or a combination of lower rates of 100GE, 200GE, and 400GE.

Key Features

800GE BASE-R PCS Core Features

PCS layer formed by bonded 2x 400GE PCS in PCS Layer
Using 32 virtual logical lanes based on 2 x 400GE PCS to reduce power in 800G operation
Well designed into using 112G/s SerDes to provide the highest port density for 800G Ethernet solution.
