Ethernet PCS 100G

Overview

Comcores PCS 100G IP core is a silicon agnostic implementation of the Physical Coding Sublayer (PCS) described in the Ethernet standard IEEE 802.3-2018 and compliant with Clause 82 of IEEE 802.3ba and Clause 91 of IEEE 802.3bj specification.

The Ethernet PCS IP supports 100G line rates, however other Ethernet PCS speeds are available, such as 1G/2.5G and 10G/25G. The IP provides an interface between the Media Access Control (MAC) and Physical Medium Attachment (PMA) through a 4 lane parallel interface and offers a CGMII interface on the other 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.
