SL74HC4046 Datasheet | System Logic Semiconductor

Phase-Locked Loop High-Performance Silicon-Gate CMOS The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The SL74HC4046 phase-locked loop contains three phase parators, a voltage-controlled oscillator (VCO) and unity gain opamp DEM OUT. The parators have two mon signal inputs, PIN, and SIGIN. Input SIGIN and PIN 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 parator 1 (an exclusive OR gate) provides a digital...
