Extracting a clock from the data stream may be an obvious way to generate a synchronization signal, but doing so is nontrivial Many common measurements require some form of timing reference to ...

The Global Positioning System (GPS), the Internet and many defense-critical applications for example—demand exceptionally precise time and frequency standards. Today’s systems, however, rely on 1950s ...

Most biochemical reactions accelerate as temperature increases, but our daily circadian rhythms, which are underlain by gene regulatory and biochemical networks, remain constant, even as temperatures ...

Synchronous interfaces involve a single clock domain and are relatively easy to design. However, at times, it is advantageous and necessary to have an asynchronous interface between peripherals for ...

With increased clock domains in modern ASICs, clock-domain crossing (CDC) has become ubiquitous, indispensable, and essential. Of course, timing is always an issue. High clock speeds and delays in ...

Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for ...

The IEEE 1588 Precision Time Protocol enables precise time synchronization over the packet-based Ethernet network so that the time on a slave clock at one end of the network agrees with a master clock ...

As sunlight filters through your window each morning, a quiet, powerful rhythm pulses inside your body. This inner clock tells you when to sleep, eat, and wake. It keeps pace with the 24-hour cycle of ...
