Clock Generators, PLLs, Frequency Synthesizers

Time and frequency management is critical in communications systems and devices, from cellular and satellite networks, to specialized communications systems, such as those used in military and aerospace applications. In order to accurately measure, generate, and control frequency and timing signals, various types of clock sources, synthesizers, and related components are used. Clock generators, Phase-Locked Loops (PLLs) and frequency synthesizers are three of the primary components used for frequency management in many communication systems and applications.

Clock Generators

Clock generators are among the most basic types of timing and frequency components. As its name suggests, a clock generator is a device that generates clocks, typically in order to provide the timing signals for other components and systems. Clock generators generate digital waveforms with precise pulse width, period, duty cycle, and timing. Clock generators are typically used to provide clock signals that are used in data conversion, data transfer protocols, and digital logic circuits. They are also used in precision measurement systems and application circuits.

Phase-Locked Loops (PLL)

Phase-Locked Loops (PLLs) represent a more sophisticated type of frequency control and management solution. A PLL is a feedback control circuit that synchronizes the phase of an output signal to the phase of an input signal. The typical architecture of a PLL includes an voltage-controlled oscillator (VCO), divider, phase detector, low-pass filter and amplifiers. There are several different types of phase detectors, but all have the same basic function of detecting the difference in phase between the input and output signals. The detected phase difference information is filtered and used to drive the VCO and adjusts its output frequency. PLLs are used to generate precise frequencies and accurately control frequency drift.

Frequency Synthesizers

Frequency synthesizers are used to generate any desired frequency across a predefined range. The generated frequency range is determined by the reference frequency of the oscillator and often requires the use of a Phase-Locked Loop (PLL). A frequency synthesizer consists of three main components: an oscillator, a divider and a phase detector. The oscillator is the source of the reference frequency, while the dividers divide down the frequency and produce the output signal. The phase detector compares the input frequency to the output frequency and generates an error signal that adjusts the oscillator frequency to match the input frequency. Frequency synthesizers are often used to generate higher or lower frequencies than the reference frequency to provide a more flexible frequency control solution.
