1.1. Features

The F-Tile Interlaken Intel® FPGA IP core supports the following features:
  • General features:
    • Compliant with the Interlaken Protocol Specification, Revision 1.2.
    • Compliant with the Interlaken Reed-Solomon Forward Error Correction (RS-FEC) Extension Specification, Revision 1.1.
    • Supports 2, 4, 6, 8, 10, and 12 serial lanes in configurations that provide up to 318.75 Gbps raw bandwidth. Refer to the Table: IP Supported Combinations of Number of Lanes and Data Rates below for more details on current list of supported configurations.
    • Supports per-lane data rates of 6.25, 10.3125, 12.5, 25.78125, and 53.125 Gbps using Intel FPGA on-chip high-speed transceivers.
  • User interface features:
    • Supports dynamically configurable BurstMax and BurstMin values.
    • Supports Packet mode and Interleaved mode for user data transfer.
    • Supports up to 256 logical channels in out-of-the-box configuration.
    • Supports multi-segment user interface.
  • Flow-control features:
    • Supports optional out-of-band flow control blocks.
    • Supports optional user-controlled in-band flow control with 1, 2, 4, 8, or 16 16-bit calendar pages.
    • Supports error correction code (ECC) for memory block implementation with the IP.
  • Line-side features:
    • Supports per-lane data rate of 53.125 Gbps using pulse amplitude modulation (PAM4) mode.
    • Supports per lane data rates of 6.25, 10.3125, 12.5, 25.78125 Gbps using non-return-to-zero (NRZ) mode.
