SL74HC4046 Phase-Locked Loop High-Performance Silicon-Gate CMOS The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
The SL74HC4046 phase-locked loop contains three phase comparators, a voltage-controlled oscillator (VCO) and unity gain opamp DEM OUT.
The comparators have two common signal inputs, COMPIN, and SIGIN.
Input SIGIN and COMPIN can be used directly coupled to large voltage signals, or indirectly coupled (with a series capacitor to small voltage signals).
The self-bias circuit adjusts small voltage signals in the linear region of the amplifier.
Phase comparator 1 (an exclusive OR gate) provides a digital er...
