3.1.8. PMA Interface
The TX PMA interface FIFO is in the datapath for all modes of operation such as:
- PMA direct
- PMA direct high data rate PAM4 modes
The two TX FIFO modes are elastic or phase compensation. Elastic mode is identical to Basic mode in L/H-tiles where you can monitor the FIFO full or empty and almost full or empty signals. The control FIFO writes and reads through the read and write enable ports.
Refer to Supported Applications/Modes for more details about these modes, and refer to the PMA Interface section for more details about the E-Tile Native PHY PMA Interface.
