FAQ about Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers
-
1. Which is better, direct digital synthesis or PLL?
Direct digital synthesis (DDS) and PLL each have their own advantages and disadvantages. Choosing which one is better depends on the specific application requirements. DDS performs well in frequency switching speed and high resolution, while PLL has more advantages in phase noise and spurious performance.
The advantages of DDS include:
High frequency switching speed: DDS works in the digital domain. Once the frequency control word is updated, the output frequency changes accordingly, and the frequency hopping rate is high.
High resolution: Due to the large width of the frequency control word (such as 48bit or higher), the frequency resolution is high.
Flexibility: DDS can generate any desired waveform and initial phase, suitable for applications requiring a wide range of scenarios.
PLL advantages include:
Low phase noise: PLL excels in low phase noise and low spurious performance, suitable for applications requiring high stable frequency.
Wide frequency range: The upper limit of the PLL output frequency depends on the upper limit of the VCO, which can support a wider frequency range.
-
2. How does PLL increase frequency?
PLL (phase-locked loop) is usually used to increase or decrease the frequency of a signal. Increasing the frequency usually involves increasing the value of the feedback divider, while decreasing the frequency involves increasing or adjusting the gain followed by a divider.

3. What are frequency synthesizers used for?
Frequency synthesizers have a wide range of applications in many fields, mainly including the following aspects:
Communication systems: In communication systems, frequency synthesizers are used to generate carrier frequencies and modulation signals to ensure the normal operation of communication equipment and the stability of signal transmission. It can provide high-precision and stable frequency signals to meet the requirements of communication systems for frequency accuracy and stability.
Radar systems: Radar systems require accurate frequency synthesis to ensure functions such as beam pointing and target tracking. Frequency synthesizers play a key role in radar systems, providing precise frequency control to ensure the performance and accuracy of radar systems.
Radio equipment: Radio equipment requires frequency synthesizers to generate signals of different frequencies for modulation and demodulation, signal transmission and reception, etc., to ensure effective communication between devices. The high accuracy and stability of frequency synthesizers enable radio equipment to work efficiently.
Instrumentation and test equipment: Frequency synthesizers are used in test and measurement applications as standard signal sources. It can generate high-precision and stable frequency signals to meet the signal quality requirements of laboratory test and measurement equipment.
Electronic countermeasure equipment: In electronic countermeasures, frequency synthesizers can be used as jammers to interfere with enemy communications and radar systems by generating signals of multiple frequencies. Its high flexibility and rapid response make it important in electronic countermeasures.
Other applications: Frequency synthesizers are also widely used in remote control and telemetry communications, navigation, and radio and television. For example, in shortwave frequency hopping communications, frequency synthesizers can quickly switch frequencies and phases to meet the requirements of fast frequency hopping communications.
