DVCO
h’f9
crystal oscillator center frequency adjustment value for line-lock
mode, true adjust value is DVCO – ADJUST.
For factory crystal alignment, using standard video signal: disable
autolock mode, set DVCO = 0, set lock mode, read crystal offset from
ADJUST register and use negative value for initial center frequency
adjustment via DVCO.
