Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers covers a range of devices used to modify a signal, usually at the source, in order to achieve a desired output frequency. This can range from a voltage-controlled oscillator (VCO) as the basis of a frequency synthesizer/PLL, to a quartz-crystal clock generator using digital logic to create a square wave signal. The applications and working principle of this technology can vary greatly.

Digital Frequency Synthesizer (DFS) is a type of clock generator which utilizes a digital computer-controlled oscillator to create High-Frequency (HF) clock signals with precision frequency resolution and accuracy. The oscillator is driven by a digital program that is stored in memory. The signal is then delivered to the output as a square wave signal. DFS is used for radio frequency frameworks, electronic warfare gear and radio communications gear.

Phase Lock Loops (PLLs) are electronic circuits used for tracking a signal or for keeping a signal in synchronization with a reference signal. A PLL produces an output signal that is kept in constant phase with the reference signal. The main component in a PLL is the programmable frequency synthesizer (also known as the VCO), which is used to generate a frequency based on the reference signal. Other components used in a PLL include an amplifier, a phase detector, a voltage-controlled oscillator, a low-pass filter, and a charge pump.

Clock Generators are another type of electronics component used to generate precise timing signals that are asynchronous to the system’s clock. Most clock generators produce a rectangular clock output, which can be used to drive logic circuitry or other devices. Clock generators are commonly used in consumer electronics, military, and aerospace applications where there is a need to generate precise signal speeds and precise signal frequencies, or to clock multiple asynchronous systems together.

Programmable Clock Generators or Multi-Output Clock Generators utilize a programmable time basis to produce multiple unique, precise frequency and timing signals. A Gated Clock Generator is a type of clock generator that can be used to temporarily stop or slow down the clock speed, when necessary. The Frequency Divider is another type of clock generator that divides an input or reference frequency by a programmable division factor to produce an output frequency for asynchronous timing.

Crystal oscillators are highly stable quartz crystal devices used as the basis of clock generators, such as quartz synchronizers, that produce a very precise signal frequency. The frequency of the clock generator is determined by the cut of the quartz crystal, which is determined by the shape and size of the quartz slab, as well as its environment. Quartz crystal clock generators are found in precision oscillator circuits, used in digital clocks and watches, and in various communications and military systems.

Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers provide a wide range of applications, allowing for the generation and synchronization of multi-frequency signals and for precise timings. The design of the circuit, application, and part type will determine the type of clock generator used in an electronic device. Sophisticated and reliable clock/timing solutions are an integral part of many of today’s electronics and communications systems.
