ion to the MC14046 Metal gate CMOS device. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC4046A phase−locked loop contains three phase comparators, a voltage−controlled oscillator (VCO) and unity gain op−amp DEMOUT. 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.
