Most electronic clocks, be they analog or digital, use a crystal oscillator (XO) based on a 32.768 kHz crystal for their reference. In fact, it is same crystal that’s commonly used as a real-time ...

RF instruments and wireless transceivers often feature an input for an external reference clock, such as the ubiquitous 10MHz reference input port found on RF instruments. Many of these same systems ...

Clock-distribution devices create multiple copies of a master clock and distribute them to a variety of integrated circuits. They accept single-ended or differential clock inputs and supply multiple ...

A clock tree is intended to generate the reference timing required by all the ICs in a PCB design and the challenge for an engineer is to design one with the fewest number of components possible, ...

Today’s complex system boards often contain application-specific processors, high-speed general-purpose processors, and multiple system-on-a-chip designs. Each of these high-performance circuits may ...
