Overview

Comcores Ethernet PCS 10G/25G IP core is a silicon agnostic implementation of the Physical Coding Sublayer (PCS) compliant with Ethernet standard IEEE 802.3-2018 and with Clause 49 of IEEE 802.3ae specification.

The Ethernet PCS 10G/25G IP supports 10G and 25G line rates, however other Ethernet PCS speeds are available, such as 1G/2.5G and 100G.

On one side, it interfaces with a SerDes device, and on the application side, it has a port for XGMII/XXVGMII Ethernet signals.

The Ethernet PCS 10G/25G IP core is verified using advanced methodologies for RTL design, verification, HW verification and interoperability testing. It has been optimized for size and is a highly tested solution that will fast track any project.
