PRODUCTION DATA.
SerDes rate = 1.25 x (M/L) x Baseband data rate x Number of bits per sample (16)
M is a JESD204B interface parameter that refers to the number of data streams from FPGA to DAC
L is a JESD204B interface parameter that refers to the number of SerDes lanes used to transmit data
1.25 is a factor due to the 8B10B encoding of the baseband data
Example,
if the baseband data rate = 2457.6 MSPS and L-M-F-S-Hd = 4-1-1-2-1
