The phase-locked loop (PLL) has become one of the most versatile tools in the communication sector. PLLs are at the heart of circuits and devices ranging from clock recovery blocks in data ...

To achieve the timing goals needed in their ASIC designs, many engineers include phase-locked loops. PLLs have a number of desirable properties that include the ability to multiply clock frequencies, ...

Phase-locked-loop (PLL) frequency synthesizers are signal sources often employed in many types of electronic equipment. They show up as clock sources in high-frequency instruments and as local ...

A phase-locked loop (PLL) is a feedback system that combines a voltage-controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or ...

Radiation-hardened phase-locked loop (PLL) circuits represent a critical advancement in safeguarding electronic systems against the deleterious effects of ionising radiation. These circuits are ...

The system in Figure 2 uses the ADF4372 PLL (see Figure 5), a wideband synthesizer with integrated VCO, that allows the implementation of fractional-N or integer-N frequency synthesizers when used ...

But taking a voltage-controlled oscillator at 100 MHz (nominal) and dividing its output by 100 will give you a signal you can lock to a 1 MHz crystal oscillator which is, of course, trivial to build.
