Power Supply Sequencing Requirements
When using the SERDES with 1.5V VCCIB or VCCOB, the SERDES should not be left in a steady state condition
with the 1.5V power applied and the 1.2V power not applied. Both the 1.2V and the 1.5V power should be applied
to the SERDES at nominally the same time. The normal variation in ramp_up times of power supplies and voltage
regulators is not a concern.
