Datasheet Summary
Phase-Locked Loop
High- Performance Silicon- Gate CMOS
The MC74HC4046A is similar in function to the MC14046 Metal gate CMOS device. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LSTTL outputs.
The HC4046A phase- locked loop contains three phase parators, a voltage- controlled oscillator (VCO) and unity gain op- amp DEMOUT. 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...
