Ethernet PCS 1G/2.5G

Overview

Silicon agnostic implementation of the Physical Coding Sublayer (PCS) compliant with Ethernet standard IEEE 802.3-2018

The Ethernet PCS 1G2.5G IP core is a silicon agnostic implementation of the Physical Coding Sublayer (PCS) compliant with Ethernet standard IEEE 802.3-2018. The IP core supports 1G and 2.5G line rates, however other Ethernet PCS speeds are available, such as 10G/25G and 100G. The IP provides an interface between the Media Access Control (MAC) and Physical Medium Attachment (PMA) through a Gigabit Media Independent Interface (GMII) or Serial Gigabit Media Independent Interface (SGMII).

On one side it interfaces to a SerDes device and on the application side it has a port for GMII/SGMII Ethernet signals.

The Ethernet PCS 1G/2.5G 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.
