SAN FRANCISCO — Claiming an industry first, EDA startup Xpedion Design Systems Inc. introduced a transistor-level phase-locked loop (PLL) solution for verifying complete closed loop noise and jitter.

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 ...

The real "showstopper" in a standard digital PLL is the interaction between the loops. In a typical design, the Phase Detector and the Frequency Detector run simultaneously.

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 ...

Behavioral modeling and simulation of a PLL based integer n frequency synthesizer has been illustrated in this paper. The synthesizer generates a signal of 5.15-5.25GHz in the UNII (Unlicensed ...

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 ...

When Hackaday runs a contest, we see all manner of clever projects. But inevitably there are some we don’t see, because their builders didn’t manage to get them finished in time. [Park Frazer]’s phase ...

ATLANTA--(BUSINESS WIRE)--Silicon Creations, a leader in high-performance analog and mixed-signal intellectual property (IP), proudly announces the achievement of over 1,000 production licenses for ...

The total power consumption of the proposed PLL is only 8.89 mW from a 1 V supply, which leads to a figure of merit of reference of -247.4 dB. Credit must be given to the creator. Only noncommercial ...

How do you ensure that every part of a system receives the clock it needs—without wasting power or sacrificing performance? The answer lies in creating a well-structured frequency plan built around a ...
