With the increasing complexity of SoCs, multiple and independent clocks are essential in the design. The design specifications require system level muxing of some of these clocks before they are sent ...

Signal integrity is one of the many challenges faced by chip designers. Deep submicron technologies are unfriendly hosts for the nice, clean signals desired. The culprits that compromise signal ...

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 ...

For example, if the positive-going edges of a clock signal are used as the timing reference for a digital circuit, then any deviation of the actual clock edges from their ideal positions constitutes ...

Delay-locked loops (DLLs) are critical components in modern electronic systems, providing robust synchronisation of clock signals in a variety of applications ranging from high-speed communication 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 ...

The beating heart of mixed-signal processing is delimited by the clock devices that slice the analog world into digital events. Like our own hearts, we don’t pay much attention to them unless ...

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 ...

TOKYO--(BUSINESS WIRE)--Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today expanded its timing solutions portfolio with a new sub-100fs ...

Harrison, born in 1693 in Lincolnshire, proposed a clock design that would solve the problem of determining longitude at sea. His proposal was vindicated last Thursday, 300 years after he first ...

However, as ASIC and SoC clock receivers become increasingly customized, these fixed-amplitude standards no longer provide an optimal balance between power consumption, noise performance and signal ...
