草榴社区 Ethernet PCS IP
The 草榴社区 Ethernet Physical Coding Sublayer (PCS) IP is compliant with the IEEE 802 and consortium specifications for 1G, 2.5G, 5G and 10G Ethernet PCS layers. The 草榴社区 Ethernet PCS core provides an interface between the Media Access Control (MAC) and Physical Medium Attachment Sublayer (PMA) through a Media independent interface. With support for GMII for 1000BASE-X PCS defined for a single lane which operates at 125 MHz to support 1000BASE-X PMA and XGMII for 10GBASE-X PCS defined for four lanes which operate at 312.5 MHz on each lane to support 10GBASE-X and 10GBASE-R PMA. To maintain transition density and DC balancing, the 1000BASE-X and 10GBASE-X PCS use 8B/10B encoding/decoding and 10GBASE-R PCS uses 64B/66B encoding or decoding and the scrambling technique.
The DWC_xpcs core is designed to support the following derivatives of the PCS layer:
- XAUI
- RXAUI
- 1000BASE-X or SGMII
- 10GBASE-X
- 10GBASE-R
- 10GBASE-KX4, 10GBASE-KR, 1000BASE-KX
The 草榴社区 Ethernet PCS IP is verified using state-of-the-art methodologies including the RTL design, verification, hardware verification and interoperability tests. The IP is easily configured with a user-friendly application interface for easy functional and implementation objectives to meet design requirements, making the 草榴社区 Ethernet PCS IP a streamlined and flexible solution. Coupled with the 草榴社区 XGMAC IP and a configurable MAC that supports 1G/2.5G/5G/10G Ethernet applications, the Ethernet PCS IP offers easy SoC integration into 1G/2.5G/5G/10G Ethernet designs.
The 草榴社区 Ethernet IP solutions consist of configurable Controllers and silicon-proven PHYs supporting speeds of up to 100G, MACsec Security Modules, Verification IP, IP Prototyping Kits, Software Development Kits and Interface IP Subsystems.

- Option to have either IEEE 802.3 Clause 45 compliant MDIO serial interface or parallel micro-controller interface for the host.
- Conversion of XGMII idle control characters to a randomized sequence of code groups to enable lane synchronization, land to lane alignment and clock rate compensation
- 8B/10B encoding to convert the binary data to 10-bit encoded data for each lane
- Lane synchronization on receive side to determine code-group boundaries
- De-skew of all received code groups to an alignment pattern with a maximum allowed skew over 5 cycles
- Clock rate compensation in which idle characters are inserted or deleted to compensate for the frequency variations between the recovered clock and the local clock with a maximum allowed variation between the clocks of 200ppm
- Supports internal loop-back on the XGMII for debugging through receive to transmit digital path and loopback control of the SerDes PHY transmit to SerDes PHY receive lane
- Link status reporting for faulty conditions and multiple options for error status and statistics available for monitoring and debugging
