1 _{Default mode. No DDCs used. 500 MSPS is L = 2, M = 1, and F = 1; 1000 MSPS is L = 4, M = 1, and F = 1. Power dissipation on DRVDD changes with lane rate and}
number of lanes used. Care must be taken to ensure that the serial line rate for a given configuration is within the supported range of 3.125 Gbps to 12.5 Gbps.
2 _{Can be controlled by the SPI.}
