Motorola 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. The self–bias circuit adjusts small voltage signals in the linear region of the amplifier.APPLICATIONS
include FM and FSK modulation and demodulation, frequency synthesis and multiplication, frequency discrimination, tone decoding, data synchronization and conditioning, voltage–to–frequency conversion and motor speed control.●
