Ethernet PCS 10G/25G


Comcores 10G/25G PCS IP core is a silicon agnostic implementation of the PCS layer described in the Ethernet standard IEEE 802.3-2018 and compliant with Clause 49 of IEEE 802.3ae specification. The IP-core is part of a family of IP-cores that are tightly integrated.


The IP-core is part of a family of IP-cores that are tightly integrated. The IP-core has been optimized for size and offers an XGMII/XXVGMII/XLGMII interface on one side and a 10-80-bit parallel interface at the PMA-side.
