Clock signals provide reference timing to every integrated circuit and electrical system. Consumer applications typically use simple quartz crystals for reference clock generation. Other applications, ...

Phase-Locked Loops (PLLs) are commonly used to perform a variety of clock processing tasks, such as clock frequency multiplication and clock deskewing. PLLs, like many other analog IP macros, come ...

A new method of phase coordinating to enhance PLL/DLL design is introduced herein. This method, known as Ultimate Phase Tracking, eliminates jitter peaking thus enabling applications like Digital FM, ...

PLLs (phase-locked loops) are common analogcircuits in SOCs (systems on chips). Almost allSOCs with a clock rate greater than 30 MHzuse a PLL for frequency synthesis. However, a“one-size-fits-all” PLL ...

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 ...

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 ...
