The DesignWare® Enterprise Ethernet Physical Coding Sublayer (PCS) IP is compliant with the IEEE 802.3 and consortium specifications for 1G, 10G, 25G, 40G, 50G and 100G Ethernet PCS layers. The IP provides an interface between the Media Access Control (MAC) and Physical Medium Attachment (PMA) sublayer through a media independent interface.
The DesignWare Enterprise Ethernet PCS IP is designed to support the following derivatives of the PCS layer:
- 100GBASE–LR4 (w/o FEC)
- 100GBASE–ER4 (w/o FEC)
- 100GBASE-SR4 (with RS-FEC)
- 100GBASE-CR4 (with RS-FEC)
- 100GBASE-KR4 (with RS-FEC)
- 50GBASE-R PCS (as per 25G Consortium Chip-2-chip & Chip-to-module CAUI-4
- 40GBASE-R PCS
- 25GBASE-KR, 25GBASE-CR (with RS-FEC, Cl74 FEC)
- 25GBASE-KR-S, 25GBASE-CR-S (with Cl74 FEC)
- 25G BASE-SR (with RS-FEC)
- 25GBASE-R PCS (Specification Revision 1.51 July 2015)
- Chip-2chip & Chip-to-module 25GAUI
- 20GBASE-R PCS
- 10GBASE-R PCS
- 1000BASE-X/SGMII
The DesignWare Enterprise Ethernet PCS IP is verified using state-of-the-art methodologies including the RTL design, verification, hardware verification, and interoperability tests. It can be easily configured with a user-friendly application interface for easy functional and implementation objectives to meet design requirements. Coupled with the configurable DesignWare Enterprise Ethernet MAC IP, the Enterprise Ethernet PCS IP offers easy SoC integration for 1G/10G/25G/40G/50G/100G Ethernet designs.
The DesignWare Ethernet IP solutions consist of configurable controllers and silicon-proven PHYs supporting speeds of up to 100G, verification IP, IP Prototyping Kits, Software Development Kits and Interface IP Subsystems.  DesignWare Enterprise 40G Ethernet PCS Controller IP
