Feature Description
Data Transfer
  • For PAM4 mode:
    • FHT supports 48 Gbps to 58 Gbps and 96 Gbps to 116 Gbps per lane with a maximum of 4 lanes.
    • FGT supports 20 Gbps to 58 Gbps per lane with a maximum of 12 lanes.
    Refer to Parameters for more details on the supported transceiver data rates for PAM4 mode.
  • For NRZ mode:
    • FHT supports 24 Gbps to 29 Gbps and 48 Gbps to 58 Gbps per lane with a maximum of 4 lanes.
    • FGT supports 1 Gbps to 32 Gbps1 per lane with a maximum of 16 lanes.
    Refer to Parameters for more details on the supported transceiver data rates for NRZ mode.
  • Supports continuous streaming (Basic) or packet (Full) modes.
  • Supports low overhead frame packets.
  • Supports byte granularity transfer for every burst size.
  • Supports user-initiated or automatic lane alignment.
  • Supports programmable alignment period.
PCS
  • Uses hard IP logic that interfaces with Intel® Agilex™ 7 F-tile transceivers for soft logic resource reduction.
  • Supports PAM4 modulation mode for 100GBASE-KP4 specification. RS-FEC is always enabled in this modulation mode.
  • Supports NRZ with optional RS-FEC modulation mode.
  • Supports 64b/66b encoding decoding.
Error Detection and Handling
  • Supports CRC error checking on TX and RX data paths.
  • Supports RX link error checking.
  • Supports RX PCS error detection.
Interfaces
  • Supports only full duplex packet transfer with independent links.
  • Uses point-to-point interconnect to multiple FPGA devices with low transfer latency.
  • Supports user-defined commands.
1 For FGT NRZ mode, 32 Gbps is not supported by the following Intel® Agilex™ 7 device OPNs:
  • AGIA027R29A1E2VR0
  • AGIB027R29A2E2VR0
  • AGIB027R29A1E2VR1
  • AGIB027R29B1E2VR2
  • AGIB027R29A1E2VR2
  • AGIB027R31B2E2VR0
  • AGIB027R31B2E3VR0
  • AGIB027R31B1E2VR0
