2. Interface Overview

This section describes various interfaces of the F-Tile PMA/FEC Direct PHY Multirate Intel FPGA IP core.
The F-Tile PMA/FEC Direct PHY Multirate Intel FPGA IP has the following interfaces:
  • Clock signals
  • Reset signals
  • TX and RX serial and parallel data signals
  • Custom Cadence control and status signals
  • TX and RX PMA status signals
  • RS-FEC signals
  • TX and RX PMA FIFO signals
  • PMA Avalon® memory-mapped interface signals
  • Datapath Avalon® memory-mapped interface signals
Some of the interfaces of the IP are fracture based. The F-Tile PMA/FEC Direct PHY Multirate Intel FPGA IP provides mapping for such interfaces from LSB to MSB. The mapping is used for all the reconfiguration groups.
Note: Some ports are only available in the Profile #0 tab.
