Wrapping up the series, in Part 3 we analyze the example hypothetical synthesizer to demonstrate the concepts and methods presented so far. Some brief theory and typical measurements of phase noise.

The phase locked loop, or PLL, is a real workhorse of circuit design. It is a classic feedback loop where the phase of an oscillator is locked to the phase of a ...

If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...

Scientists have developed an advanced phase-locked loop (PLL) frequency synthesizer that can drastically cut power consumption. This digital PLL could be an attractive building block for Bluetooth Low ...

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 ...

Santa Clara, Calif. – January 11, 2012 – Redfern Integrated Optics, a global leader in single frequency narrow linewidth lasers and laser systems, today announced that the United States Patent & ...
