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 ...
Configuring a phase locked loop (PLL) for a given frequency synthesis application can simultaneously be both a quick-and easy-process as well as a time-consuming, tedious, and iterative process. This ...
A special technique produces very wide loop BWs in high-frequency PLLs (and hence, indirect (PLL) synthesizers), thereby achieving very low phase noise rivaling that of direct (MMD) synthesizers. A ...
An important task for a digital communications receiver is to remove any frequency/phase offsets that might exist between the transmitter and receiver oscillators. Designers typically implement a ...
Fractional-N PLLs are a useful class of PLLs and not well understood. This paper explains in simple terms how these differ from a regular integer PLL. Common applications are listed along with a brief ...
Microwave frequency generation has posed significant challenges to engineers over the years, requiring in-depth knowledge of analog, digital, and radio frequency (RF) and microwave ...
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 ...
This is Part 1 of a three-part series. As modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher performance than ever before, they’re ...
