The 17³Ô¹Ï 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 17³Ô¹Ï 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 17³Ô¹Ï 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 17³Ô¹Ï Ethernet PCS IP a streamlined and flexible solution. Coupled with the 17³Ô¹Ï 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 17³Ô¹Ï 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.

- Backplane Ethernet for KX and KX4, KX only or KX4 only with KX configurations capable of 2.5 Gigabit Ethernet speeds simply by increasing the clock frequency
- Conversion of dual data rate XGMII to single data rate 312.5 MHz data-bus
- Optional conversion of double data width (64 bit) XGMII operation with 156.25 MHz clock to single data rate (32-bit) operating with 312.5 MHz clock
- Seamlessly integrates with the 17³Ô¹Ï XAUI-PHY SerDes
- 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
