1.4.3.1. F-Tile Features and Capabilities

The Agilex™ 7 F-tile transceivers are general purpose transceivers. .

The F-tile transceivers have the following two usage modes:

  • 4 channels up to 112G PAM4 + 12 channels up to 58G PAM4
  • 4 channels up to 112G PAM4 + 16 channels up to 32G NRZ

They have multiprotocol support for:

  • CEI
  • Ethernet
  • CPRI
  • FlexE
  • Interlaken
  • Fibre Channel
  • SRIO
  • SerialLite IV
  • OTN
  • JESD204B/C
  • FlexO
  • IEEE1588
  • GPON
  • SDI
  • Vby1
  • HDMI
  • Display Port.

In addition, F-tile transceivers support PCIe Gen4 x16 with the P-Tile equivalent features, precise time management, and PMA direct mode.
