This application note discusses phase frequency detector characteristics that affect phase-locked loop (PLL) dead band and jitter performance. In PLLs that employ charge pump loop filter designs the ...

The purpose of a phase locked loop (PLL) is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned ...

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.

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 ...

A general-purpose vector signal analyzer offers a low-cost, flexible option for measuring the frequency settling time of PLLs. By Douglas Olney, Keithley Instruments Inc. The frequency-settling time ...

While analog phase-lock loops (PLLs) still have a home in communication equipment, there is a clear shift in the sector toward implementing digital PLLs (DPLLs) in comm ASIC designs. For example, in ...

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 ...

I had never heard of the 74HCT9046 phase-locked loop before a fortnight ago, and now I own one. To my shame, it was apparently released by Phillips (now Nexperia) around 20 years ago – that said, the ...

That big grandfather clock in the library might be an impressive piece of mechanical ingenuity, and an even better example of fine cabinetry, but we’d expect that the accuracy of a pendulum timepiece ...
