MC74HC4046A
Phase-Locked Loop
High鈥揚(yáng)erformance Silicon鈥揋ate CMOS
The MC74HC4046A is similar in function to the MC14046 Metal
gate CMOS device. The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with
LSTTL outputs.
The HC4046A phase鈥搇ocked loop contains three phase
comparators, a voltage鈥揷ontrolled oscillator (VCO) and unity gain
op鈥揳mp DEMOUT. 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鈥揵ias 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鈥揺dge 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 VCOOUT 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鈥揳mp output DEMOUT 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 op鈥揳mps 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鈥搕o鈥揻requency conversion and motor speed control.
