CXA3106Q
ωn and ζ calculated for various types of computer signals are shown below.
Here, the various parameters are as follows.
FSYNC: Input H sync frequency
FCLK: Output clock frequency
KPD 2π: Phase comparator gain 2π
KVCO/2π: VCO gain
(KPD*2π = +100 or 400 or 1600)
(when VCO DIV = 1/1, KVCO/2π = 50)
(when VCO DIV = 1/2, KVCO/2π = 50/2)
(when VCO DIV = 1/4, KVCO/2π = 50/4)
N: Counter value
C1: Loop filter capacitance value
R1: Loop filter resistance value
