Ethernet PCS 10G/25G

Overview

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

The PCS IP provides an interface between the Media Access Control (MAC) and Physical Medium Attachment (PMA) through a XGMII or XXVGMII Interface, and a default 40-bit parallel interface at the PMA-side.

The PCS 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.
