2.2.6. Reed Solomon Forward Error Correction (RS-FEC) Parameters
The Native PHY IP Core supports RS-FEC (528, 514) and (544, 514). You can enable
this functionality by selecting the Enable RS-FEC option in the Datapath Options
section of the GUI.
Figure 22.
GUI with Enable RS-FEC Option Selected
RS-FEC merging is not supported with more than one Native PHY IP instance. A Native
PHY IP with an RS-FEC block enabled uses the whole RS-FEC block, even if it uses
only one channel in the IP. You can use dynamic reconfiguration to utilize the same
RS-FEC block for implementation on different protocols.
The RS-FEC IP core supports the following modes:
•
32GFC/ CPRI 24G (x1, x2, x3, x4)
•
128 GFC
•
25GE FEC Direct (x1, x2, x3, x4)
•
100 GbE
