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 ...

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.

The original GPS signals, and indeed most GPS signals including L5, utilize conventional pseudonoise (PN) signal code division multiple access (CDMA), some with both in-phase and quadrature-phase ...

Some brief theory and typical measurements of phase noise. How to produce the lowest phase noise at a PLL output. A standard design procedure for a typical Type 2, second-order loop. As stated in ...

Phase lock loops (PLLs) play a key role in today's thriving RF industry. Commonly employed to address various timing requirements in ASIC designs, these basic building blocks allow designers to ...
