  1. The values listed are the rounded results of the calculated equation (2 × RINGPLL_Frequency)/Subrate_Divider.
  2. The highest supported line rate when using the RPLL to drive the datapath is 12.5 Gb/s.
  3. The values listed are the rounded results of the calculated equation (2 × LCPLL_Frequency)/(Output_Divider × Subrate_Divider).
