Filter design considerations for PC1 and PC2 of the HCT9046A
Figure 30 shows some examples of passive and active filters to be used with the phase comparators of the HCT9046A.
Transfer functions of phase comparators and filters are given in Table 4.
Table 4 Transfer functions of phase comparators and lters.

PC1
a.
passive lter
without
damping
b.
passive lter
with damping
τ
1 = R3 × C2;
τ2 = R4 × C2;
τ3 = R4 × C3;
A = 105 = DC gain amplitude
c.
active lter
with damping
PC2
d.
passive lter
with damping
A = 105 = limit DC gain
τ
1 = R3' × C2;
τ
2 = R4 × C2;
τ
3 = R4 × C3;
R3' = Rb/17;
Rb = 25 to 250 k
e.
