5.2. Enhanced PCS Architecture

Intel® Stratix® 10 transceivers support the following PCS types:

  • Enhanced PCS
  • Standard PCS
  • PCI Express Gen3 PCS

You can use the Enhanced PCS to implement multiple protocols that operate up to 17.4 Gbps line rates on GX channels.

The Enhanced PCS provides the following functions:

  • Performs functions common to most serial data industry standards, such as word alignment, block synchronization, encoding/decoding, and framing, before data is sent or received off-chip through the PMA
  • Handles data transfer to and from the FPGA fabric
  • Internally handles data transfer to and from the PMA
  • Provides frequency compensation
  • Performs channel bonding for multi-channel low skew applications
