74HC4046A
Phase-Locked Loop
High-Performance Silicon-Gate CMOS
The device inputs are compatible with standard CMOS outputs; with
pullup resistors, they are compatible with LS/ALSTTL outputs.
The
KK
74HC4046A phase-locked loop contains three phase
comparators, a voltage-controlled oscillator (VCO) and unity gain op-
amp DEM
OUT
. The comparators have two common signal inputs,
COMP
IN
, and SIG
IN
. Input SIG
IN
and COMP
IN
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 PC1
OUT
and
maintains 90 degrees phase shift at the center frequency between SIG
IN
and COMP
IN
signals (both at 50% duty cycle). Phase comparator 2 (with
leading-edge sensing logic) provides digital error signals PC2
OUT
and
PCP
OUT
and maintains a 0 degree phase shift between SIG
IN
and COMP
IN
signals (duty cycle is immaterial). The linear VCO produces an output
signal VCO
OUT
whose frequency is determined by the voltage of input
VCO
IN
signal and the capacitor and resistors connected to pins C1A,
C1B, R1 and R2. The unity gain op-amp output DEM
OUT
with an external
resistor is used where the VCO
IN
signal is needed but no loading can be tolerated. The inhibit input, when high,
disables the VCO and all on-amps to minimize standby power consumption.
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.
