What is a PLL?
A PLL, or phase-locked loop, is an electronic circuit with a current or voltage-driven oscillator which is constantly adjusted in order to match the phase of the frequency of an input signal. A PLL is used for frequency control. It is a feedback circuit that is designed in order to allow a circuit board to synchronize the phase of its on board clock with an external timing signal. Phase lock loop circuits work by comparing the phase of an external signal to the phase of a clock signal that is produced by a voltage controlled crystal oscillator. The circuit adjusts the phase of the oscillator’s clock signal in order for it to match the phase of the reference signal.
Types of PLLs
There are several different kinds of PLLs at Future Electronics. We stock many of the most common types categorized by several parameters including frequency range, supply current, supply voltage, phase noise and packaging type. Our parametric filters will allow you to refine your search results according to the required specifications.

Applications for PLLs:
PLL circuits can be set up as frequency multipliers or dividers, tracking generators, clock recovery circuits or demodulators. Phase locked loops can be found in computers, radio, telecommunications and other electronic applications. PLLs can be used in order to recover a signal from a noisy communication channel, for frequency synthesis or to distribute clock timing pulses in digital logic designs. PLLs are also used for synchronization: in space communications for demodulation, bit synchronization and symbol synchronization. Other applications include demodulation of AM and FM signals, DTMF decoders, modems, remote controls and telecommunications.
