The CD74HC4046AM96 is an integrated circuit (IC) compatible with the CMOS logic family. It is a phase-locked loop (PLL) frequency synthesizer, capable of generating frequencies up to 125MHz. It includes both a voltage controlled oscillator (VCO) and a phase-frequency detector (PFD) to create a very stable and accurate output waveform.

The CD74HC4046AM96 is used in many applications from digital clock generators, to GPS tracking systems and frequency hopping radio receivers. It is an essential component in any digital circuit design which requires precise timing signals.

Application Field

The CD74HC4046AM96 is designed for use in a variety of applications where precision, accuracy and stability of clock signals and timing data is required. This includes applications such as:

• Clock Generators
• Data Communications
• Network Clocks
• Wireless Sensor Networks
• Signal Processing
• Mobile Telephone Systems
• Radio Control Systems
• GPS Tracking Systems
• Frequency Hopping Radio Receivers

The CD74HC4046AM96 is also suitable for use in automotive and industrial applications, where the stability and accuracy of timing signals and data needs to be reliable.

Working Principle

The CD74HC4046AM96 works by providing a precision oscillator with a frequency control input, allowing it to be used as a variable frequency oscillator. The user has two controls: a voltage-controlled oscillator (VCO) control voltage, and a voltage-controlled frequency (VCF) control voltage.

The VCO generates a fixed-width pulse train in response to the VCO control voltage. The frequency of the VCO is set according to the VCF control voltage. This enables the CD74HC4046AM96 to generate nearly any frequency between approximately 10kHz and 125MHz, depending on the input voltage.

The CD74HC4046AM96 also includes a phase-frequency detector (PFD) which monitors the stability and accuracy of the output waveform. The PFD compares the phase and frequency of the input to the phase and frequency of the output, and adjusts the output frequency accordingly. This ensures that the output waveform remains accurate and consistent at all times.

The CD74HC4046AM96 is designed for use in applications where precision and accuracy are essential. The integrated PFD ensures that any fluctuations in the output waveform are monitored and corrected in real time, providing a stable and accurate output waveform at all times.
