Superior jitter tolerance with fast lock time
On-Die Instrumentation—
Eye Viewer and Jitter Margin
Tool
Simplify board bring-up, debug, and diagnostics with non-intrusive, high-resolution eye
monitoring (Eye Viewer). Also inject jitter from transmitter to test link margin in system.
Dynamic Reconfiguration Allows for independent control of each transceiver channel Avalon memory-mapped
interface for the most transceiver flexibility.
Multiple PCS-PMA and PCS-
Core to FPGA fabric interface
widths
8, 10, 16, 20, 32, 40, or 64 bit interface widths for flexibility of deserialization width,
encoding, and reduced latency
1.8.2. PCS Features
Intel Stratix 10 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 28.3 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.
