What are the key features of CD74HC4046AM96E4?
- Dual phase comparator design (XOR and edge-triggered) provides flexible phase detection modes for lock-range and noise-immunity optimization in PLL loop filter design
- VCO operating range up to 17 MHz at 5V supply with external R and C programming enables frequency synthesis from audio to high-speed digital clock rates
- Wide 2V to 6V operating range allows direct use in 3.3V and 5V systems with CMOS-compatible input thresholds for clock generation and FM demodulation circuits
What is CD74HC4046AM96E4 used for?
The CD74HC4046AM96E4 is used in clock multiplication, frequency synthesis, and clock recovery circuits where a phase-locked loop must track an input reference frequency from DC to 17 MHz. Its dual phase comparator design makes it applicable to both FM demodulation in radio receivers and jitter-tolerant clock regeneration in digital communication interfaces such as RS-485 or UART baud rate recovery. The 16-pin SOIC package and external VCO component programmability allow flexible loop bandwidth tuning for industrial control systems, motor drive synchronization, and embedded timing generation.

Frequently Asked Questions
What VCO frequency range does CD74HC4046AM96E4 support, and how is it set by external components?
The CD74HC4046AM96E4 VCO operates from near DC to approximately 17 MHz at a 5V supply, with the center frequency and range set by external resistors R1, R2 and capacitor C1 connected to the VCO IN and timing pins. Choosing R1 = 10 kOhm and C1 = 1 nF yields a center frequency near 2 MHz, while reducing C1 to 100 pF shifts the center frequency to 15 MHz, covering most digital clock recovery and frequency synthesis needs.
How do the two phase comparators in CD74HC4046AM96E4 differ, and when should each be used?
Phase Comparator 1 (PC1) uses XOR logic, providing a phase-difference output that is sensitive to both edges and duty cycle, yielding a lock range of 0 to f_VCO/2. Phase Comparator 2 (PC2) is an edge-triggered sequential detector that locks only on rising edges, offering a wider capture range equal to the full VCO range and zero static phase error. PC2 is preferred for digital clock recovery where input duty cycle varies, while PC1 suits applications requiring narrow bandwidth FM demodulation.
Can CD74HC4046AM96E4 recover a 9600 baud UART clock from an asynchronous data stream?
Yes. By configuring the VCO center frequency near 9600 Hz with an appropriate RC filter and using Phase Comparator 2 for edge-triggered lock, the CD74HC4046AM96E4 can synchronize to the 9600 baud transition rate. A loop filter time constant of approximately 1 ms (100 kOhm and 10 nF) provides stable lock within 10 bit periods while rejecting noise on the UART data line, enabling bit-synchronous clock extraction without a dedicated UART clock source.
How does CD74HC4046AM96E4 compare to CD4046B for a 5V clock multiplier design running at 10 MHz?
The CD74HC4046AM96E4 uses high-speed CMOS logic with propagation delays below 15 ns at 5V, enabling reliable PLL operation at 10 MHz with a supply as low as 2V. The CD4046B metal-gate CMOS version has a maximum VCO frequency of only 1.4 MHz at 5V and propagation delays above 80 ns, making it unsuitable for 10 MHz applications. At the same 5V supply, the CD74HC4046A achieves over 12 times higher VCO frequency than CD4046B while maintaining pin-compatible SOIC-16 footprint.
