Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

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 ...

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 ...

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 ...

Editor's note: Signal Chain Basics is an ongoing and popular series; click here for a complete, linked list of all installments.) In Signal Chain Basics Part 56 we discussed the fundamental ...

Among many deliberations when designing with high-speed analog-to-digital converters (ADCs), the effect of the ADC’s sampling clock is paramount to meeting specific design requirements. There are ...

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 ...
