2.2.6.3. 25 GbE FEC Direct Mode

Figure 27.

25 GbE FEC Direct Mode Settings

The RS-FEC is enabled in fractured mode.

2.2.6.4. Interlaken Mode

The RS-FEC is available in 100G Interlaken mode. In the 100G Interlaken mode, you

must set the RS-FEC to aggregate mode across all four lanes with transcoder bypass

enabled. The modulation scheme for this mode is PAM4.

Note: 

You must enable a special Quartus.ini file to use this mode. For more details, contact

My Intel support.

2.2.7. Reset Parameters

The Native PHY IP Core reset parameters provide reset control for the PMA interface

and adapter.
