Rising clock speeds and tighter signal timing has increased demand for accurate high-frequency modules. The PLL (phase-locked loop), which generates a high-frequency output signal based on an input ...

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 ...

Editor's Note: Although the primary target market for the 86100CU-400 application presented below is for ASIC/SoC designs, I'm assured by the folks at Agilent that this application is also applicable ...

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 ...
