SC14046B - ON Semiconductor

SC14046B Phase Locked Loop

SC14046B Phase Locked Loop The SC14046B 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.
