1.9.2. PCS Features

Intel® Stratix® 10 MX PMA channels interface with core logic through configurable and bypassable PCS interface layers.

The PCS contains multiple gearbox implementations to decouple the PMA and PCS interface widths. This feature provides the flexibility to implement a wide range of applications with 8, 10, 16, 20, 32, 40, or 64 bit interface width between each transceiver and the core logic.

The PCS also contains hard IP to support a variety of standard and proprietary protocols across a wide range of data rates and encoding schemes. The Standard PCS mode provides support for 8B/10B encoded applications up to 12.5 Gbps. The Enhanced PCS mode supports 64B/66B and 64B/67B encoded applications up to 17.4 Gbps. The enhanced PCS mode also includes an integrated 10GBASE-KR/40GBASE-KR4 Forward Error Correction (FEC) circuit. For highly customized implementations, a PCS Direct mode provides an interface up to 64 bits wide to allow for custom encoding and support for data rates up to 28.9 Gbps.

For more information about the PCS-Core interface or the double rate transfer mode, refer to the Intel® Stratix® 10 L- and H-Tile Transceiver PHY User Guide, and the Intel® Stratix® 10 E-Tile Transceiver PHY User Guide.
