3.1.1. PMA Direct Supported Modes
The F-Tile PMA/FEC Direct PHY Intel® FPGA IP supports the following for PMA Direct mode:
- Supports FGT with NRZ and PAM4 modulation. 18
- Supports FHT with NRZ and PAM4 modulation
- Supports PMA clocking mode and System PLL clocking mode
- Supports Duplex, TX simplex, and RX simplex modes
- Supports TX simplex and RX simplex for both PMA Clocking and System PLL Clocking modes. Supports 8, 10, 16, 20, 32 and 64-bit PMA data widths for simplex mode.
- Supports bonding mode for NRZ and PAM4 modulation modes
- Supports configurable FIFO modes: PMA interface FIFO, F-tile interface FIFO, Core interface FIFO-elastic, phase compensation, and register modes
- Supports configuring multiple hard IP block PMA and FEC instances within one IP instance
- Supports TX and RX de-skew if the number of streams per PMA exceeds one
- Supports up to 12 Preset modes.
