Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

As consumers thirst for the high-definition experiences delivered by expanding amounts of signal bandwidth, design challenges related to clocking become increasingly difficult and complicated. The ...

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock ...

With the advances of highly phase coherent lasers, optical atomic clocks containing multiple atoms have demonstrated stability that reaches the standard quantum limit (SQL) set by the available atom ...

Clock speed is equivalent to data movement in applications that receive and process hundreds of megabytes of data each second. Applications involved in moving enormous volumes of data include cellular ...

Clocks are power- and area- hungry, and difficult to distribute in a controlled manner. What is being done to reign in these unwieldy beasts? The synchronous digital design paradigm has enabled us to ...

At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it’s fraught with the most problems at the ...

In the case of a clock signal, these events can be adjacent positive-going edges. By using counters or pattern triggering, the same bit in a complex pattern can be repeatedly measured and the values ...

Mixed-signal printed circuit boards (PCBs) present unique challenges in high-performance applications, such as vibration analysis and other multi-channel data acquisition systems. Nonlinear ...

Timing relationships between signals are critical to reliable operation of digital designs. With synchronous designs, the timing of the clock signal relative to data signals is especially important.

The most accurate clock in space launches within days and will begin building a highly synchronised network out of the best clocks on Earth. But the project, decades in preparation, will only operate ...
