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 amplifier. Phase
comparator 1 (an exclusive OR gate) provides a digital error signal PC1out,
and maintains 90
°
phase shift at the center frequency between PCAin and
PCBin signals (both at 50% duty cycle). Phase comparator 2 (with leading
edge sensing logic) provides digital error signals, PC2out and LD, and
maintains a 0
°
phase shift between PCAin and PCBin signals (duty cycle is
immaterial). The linear VCO produces an output signal VCOout whose
frequency is determined by the voltage of input VCOin and the capacitor and
resistors connected to pins C1A, C1B, R1, and R2. The source–follower
output SFout with an external resistor is used where the VCOin signal is
needed but no loading can be tolerated. The inhibit input Inh, when high,
disables the VCO and source follower to minimize standby power
consumption. The zener diode can be used to assist in power supply
regulation.
Applications include FM and FSK modulation and demodulation, fre-
quency synthesis and multiplication, frequency discrimination, tone decod-
ing, data synchronization and conditioning, voltage–to–frequency
conversion and motor speed control.
