Product specification

74HC/HCT4046A

VDEMOUT = VPC2OUT = V----π-C---C-- ( φSIGIN – φCOMPIN)

φDEMOUT = (φSIGIN − φCOMPIN).

Fig.6 Phase comparator 1: average output voltage versus input phase difference.

Fig.7 Typical waveforms for PLL using phase comparator 1, loop locked at fo.

VDEMOUT = VPC2OUT = V--4---C-π--C-- ( φSIGIN – φCOMPIN)

φDEMOUT = (φSIGIN − φCOMPIN).
