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.

Xpedion Design Systems announced what it says is the industry's first transistor-level phase-locked loop (PLL) solution for verifying complete closed loop noise and jitter. This allows PLL designers ...

The performance of analogue phase-locked loops (PLLs) has steadily improved with operating frequencies extending to 8GHz and beyond. Recently, digital PLLs based on direct digital synthesis (DDS) have ...

A PLL (phase-locked loop) is perhaps the most widely used analog circuit in SOCs (system-on-a-chip). Almost all SOCs with a clock rate over 30MHz use a PLL for frequency synthesis. Most SOCs use more ...

Few topics in electrical engineering have demanded as much attention over the years as the phase-locked loop (PLL). The PLL is arguably one of the most important building blocks necessary for modern ...

Phase-locked-loop (PLL) frequency synthesizers are signal sources often employed in many types of electronic equipment. They show up as clock sources in high-frequency instruments and as local ...

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 ...
