PCIe has been around since 2004. It’s a high-speed serial computer expansion bus specification that replaces older PCI and PCI-X standards. PCIe currently supports the Generation 4 specification. In ...

Data converters are critical elements in communication systems forming bridges between analog transmission media such as fiber optics, microwave, RF, and digital processing blocks such as FPGAs and ...

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 ...

first half wave and a second half wave representing the received RF signal.

The heart of NIST’s next-generation miniature atomic clock ticking at high “optical” frequencies is this vapor cell on a chip, shown next to a coffee bean for scale. The glass cell (the square window ...

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 ...

At OFC 2026 (Booth #5617, West Hall), Mixed-Signal Devices will demonstrate its latest multi-gigahertz oscillator and multi-output clock-generation solutions designed to meet the timing requirements ...

Physicists at the National Institute of Standards and Technology (NIST) and partners have demonstrated an experimental, next-generation atomic clock--ticking at high "optical" frequencies--that is ...
