Ethernet PCS 1G/2.5G

Overview

Comcores PCS IP core is a silicon agnostic implementation of the PCS layer compliant with Ethernet standard IEEE 802.3-2018. The IP core supports 1G and 2.5G line rates. 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 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.

PTP profiles for 5G networks

Niklas Meyer Mortensen Jan 04 2022 The IEEE 1588 PTP standards provide a wealth of options and the basis for highly reliable and accurate time synchronization solutions. However, the time synchronization needs of specific applications in different industries can vary quite significantly. These specific needs are defined in separate PTP profile standards, often in collaboration with other industry standards organizations. For 5G, both IEEE and ITU-T provide relevant profiles that can be used to...
