Description
The CD74HC4046AM96 is a high-speed CMOS phase-locked loop (PLL) IC designed for frequency synthesis, clock recovery, and modulation/demodulation. Key features:
- Wide operating voltage (2V–6V)
- Low power consumption (HC-series CMOS)
- Three PLL stages:
- PC1 (Phase Comparator 1): XOR-based, good for noise rejection.
- PC2 (Phase Comparator 2): Edge-triggered, avoids false locks.
- PC3 (Phase Comparator 3): RS flip-flop, suited for FSK demodulation.
- On-chip VCO (Voltage-Controlled Oscillator) with adjustable frequency via external components.
- Applications: Clock synchronization, FM demodulation, tone decoding, and frequency multiplication.
Packaged in SOIC-16 (M96 suffix), it’s ideal for space-constrained designs. For stable operation, ensure proper decoupling and adhere to recommended external component values.
