Signal integrity is the art of getting a signal from point A to point B with minimum distortion to that signal. The recent attention on this subject stems from the necessity to build systems with ever ...

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 ...

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 ...

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 ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

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 ...
