DATA SHEET www.onsemi.com Phase Locked Loop MC14046B The MC14046B phase locked loop contains two phase comparators, a voltage controlled oscillator (VCO), source follower, and zener diode.
The comparators have two common signal inputs, PCAin and PCBin.
Input PCAin 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 amplifi
