THIS ASSUMES NO NOISE IS PRESENT AT THE INPUTS TO THE ADN2855 BETWEEN BURSTS.

IF THIS IS THE CASE, THE RESET PULSE MUST BEASSERTED UNTIL THE TIME THAT THE

INPUT DATA TO THE ADN2855 BECOMES VALID, IDEALLY JUST PRIOR TO THE START OF THE

PREAMBLE. THERE IS NO REQUIREMENT THAT FOLLOWING THE DEASSERTION OF THE

RESET SIGNAL THE ADN2855 MUST SEE AT LEAST 13 BITS OF THE PREAMBLE.
