Frequently Asked Questions
What is the VCO frequency range of CD74HC4046AE and how is it set by external components?
The CD74HC4046AE VCO operates across a frequency range that extends up to approximately 18 MHz at a 6 V supply. The center frequency and lock range are set by two external resistors (R1 and R2) and a capacitor (C1) connected to dedicated VCO pins. For example, a 100 pF capacitor with appropriate resistors can tune the center frequency to several megahertz, giving designers precise control over the PLL operating window.
How many phase comparators does CD74HC4046AE include, and when would you choose PC2 over PC1?
CD74HC4046AE includes 3 phase comparators: PC1 (XOR type) and PC2 (edge-triggered phase-frequency detector). PC2 is preferred in most PLL designs because it provides a frequency error signal outside the lock range, allowing the loop to pull in from any starting frequency. PC1 is chosen in applications like FM demodulation where a linear phase-to-voltage characteristic over a ±90° range at a fixed frequency is needed.
Can CD74HC4046AE be used in 3.3 V systems, and what minimum supply does it support?
CD74HC4046AE operates from a supply voltage range of 2 V to 6 V, making it compatible with 3.3 V logic systems commonly used in modern microcontrollers and FPGAs. At 2 V operation the maximum VCO frequency is reduced, but the device remains functional. At 3.3 V it offers a good balance of speed — up to approximately 10 MHz — and low power consumption for battery-operated clock-generation circuits.
