Design of advanced digital systems requires a thorough understanding of clock management circuits. The synchronous design methodology is built on the premise of a reliable clock distribution scheme.

Clock and Data Recovery (CDR) circuits form a critical component in modern digital communication systems, where the accurate extraction of timing information from data streams is paramount. These ...

In theory, synchronous clock multiplication is an easy task. A simple PLL with two digital dividers—one inserted just after the VCO (voltage-controlled oscillator) and the second one placed directly ...

Lack of coordination between asynchronous resets and synchronous logic clocks leads to intermittent failures on power up. In this series of articles, we discuss the requirements and challenges of ...

Laying the proper clock network architecture foundation makes all the difference for the best performance, power, and timing of a chip, particularly in advanced node SoCs packed with billions of ...

Lack of coordination between asynchronous resets and synchronous logic clocks leads to intermittent failures on power up. In this series of articles, we discuss the requirements and challenges of ...

Jitter can seriously degrade system operation but, as Lee Morgan explains, characterising and troubleshooting jitter on embedded systems has become a lot easier. Clocks are the heartbeats of embedded ...

Wire delay is beginning to dominate gate delay in current CMOS technologies. According to Moore’s Law by 2016 CMOS feature size should be on the order of 22 nm with clock frequencies reaching around ...
