1.1.1. Reconfiguration Group

A reconfiguration group is a set of single or multiple PMA lanes (transceivers), with different RS-FEC options, from which you can dynamically reconfigure your design. Each reconfiguration group defines the base profile (Profile #0) and a list of secondary profiles (Profile #1, Profile #2 .. to Profile #32).

The Reconfiguration group options are defined with the notation of G-Y Reconfigurable, where:
  • Y is the total number of PMA lane count allocated for the reconfiguration group.
For example, 50G-1 Reconfigurable group setting indicates that a 50G fracture (st_x2) is selected with one PMA lane configured for this reconfiguration group. You can also select a portion of the 50G fracture that is a lower rate, such as a 25G fracture (st_x1) in your reconfiguration profiles under the Reconfiguration subset parameter.
With the 50G-1 Reconfigurable group setting, you can configure your reconfiguration profiles to any of the following settings to suit your application. For example:
  • You can select a 50G fracture (st_x2) with data rate of 53.125 Gbps for the Ethernet protocol.
  • You can select a 25G fracture (st_x1) with data rates of 25.78125 Gbps and 10.3125 Gbps for Ethernet protocol.
  • You can select a 25G fracture (st_x1) with data rates of 24.33024 Gbps, 10.1376 Gbps, 9.8304 Gbps, 4.9152 Gbps and 2.4576 Gbps for CPRI protocol.
For more information about the Reconfiguration subset parameter refer to Parameter Settings: Profile #N (N=0-32) Tab. For more information about the fracture types, refer to the F-Tile Architecture and PMA and FEC Direct PHY Intel FPGA IP User Guide.
