crystal oscillator center frequency adjustment value for line-locked
mode, true adjust value is DVCO – ADJUST.
For factory crystal alignment, using standard video signal:
set DVCO = 0, set lock mode, read crystal offset from ADJUST
register and use negative value for initial center frequency adjust-
ment via DVCO.
