n =2 fn(KHz)=
Ichpump(uA) x Kvco_ac(KHz/V) / C(nF)

Cf=C/16
4 - PLL Dampi ng f a c t o r c a l c u l a t i o n s :
P = E-3 x Rf (KOhms) x C(nF) x fn(KHz)

5 - Advance ti m i ng:
+ 6
Tadv(nsec) = RADV (KOhms)*10 - 10
W here RADV i s r e s i s t a n c e f r o m RADV1 or RADV2 to ground.
Exampl e C: RADV=10Kohms wi l l r esul t i n Tadv=10*10 - 10 =90 nsec .
+ 6=106 nsec.
6- Dead t i me cal c u l a t i o n s :
Td(nsec)=0.69*Cdt(pF)*(Rdt(KΩ)+0.15) (For Vdd=5V)
Td(nsec)=0.69*Rdt(KOhms)*Cdt(pF) + 5 (For Vdd=5 V)
W here Rdt is resistance between pins DTIN1 and DTOUT1 or DTIN2 and
DTOUT2. Cdt i s c a p a c i t a n c e f r o m DTI N1 or DTI N2 t o ground.
Example D: Rd=2KW and Cdt=100pF will result in Td=148.35nsec.
