3.2. Sub Profile Parameters Validation

You must configure the Profile 0 (Power Up profile) using the following parameters before configuring the Sub Profiles:
  • System PLL Frequency
  • CPRI Rate
  • Enable Reconfiguration to 8b/10b Datapath
The F-Tile CPRI PHY Multirate Intel® FPGA IP validates the dynamic reconfiguration parameters based on the following rules:
  • CPRI rate must be unique among the sub profiles.
  • Maximum number of sub profiles is the number of available lower CPRI rates than the Profile 0 (Power Up profile).
