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
(KPD
× 2π = + 100 or 200 or 400 or 800)
KVCO/2
π
: VCO gain
(when VCO DIV = 1/1, KVCO/2
π = 75)
(when VCO DIV = 1/2, KVCO/2
π = 75/2)
(when VCO DIV = 1/4, KVCO/2
π = 75/4)
(when VCO DIV = 1/8, KVCO/2
π = 75/8)
N : Counter value
C1 : Loop filter capacitance value
R1 : Loop filter resistance value
* Consult your Sony representative for use other than noted above.
