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 ...

Researchers have shown, for the first time, that transmission of ultrastable optical signals from optical clocks across tens of kilometers of deployed multicore fiber is compatible with simultaneous ...

A recent blog post discussed the challenges of clock signal integrity and clock jitter in deep submicron semiconductor devices. Nice, clean clock signals are degraded due to many factors, including ...

RF absorption and PLL phase calibration help phased-array subsystems reduce clock spurs while preserving spectral purity and ...

Clocks are the heartbeats of embedded systems, providing timing references and synchronization between components, subsystems, and entire systems. Incorrect clock signal amplitudes and timing can ...

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 ...

High performance clock buffers – those without phase-locked loops (PLLs) – are often used in communications designs for duplication, distribution and fanout of clock signals. Sensitivity to long-term ...

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 ...

The importance of timing requirements and jitter budgets for FPGAs, ASICs, and SoCs. How to utilize the information portrayed in a clock tree to choose the most well-suited clock generator for your ...

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.
