VSDT

AGC – DVCO

h’b2

sync amplitude reference (0: AGC disabled).

Write 0 to register h’b5 after writing 0 to AGCREF to disable the AGC

GAIN

h’58

crystal oscillator center frequency adjust, –2048..2047

DVCO

h’59

crystal oscillator center frequency adjustment value for line lock mode.

true adjust value is DVCO – ADJUST.

For factory crystal alignment:

set DVCO=0, set lock mode, read crystal offset from ADJUST register

and use negative value for initial center frequency adjustment via

DVCO.
