Out of the many scenarios in which a multiplexer may be present in a clock path, the following two are most commonly found: Multiplexer used for clock selection / Input-based clock multiplexer ...
For systems that implement the Spread Spectrum Clock option specified in PCI Express, the clock recovery circuit also has to track the frequency fluctuation caused by the Spread Spectrum Clock. Once ...
Output of the switches and the delayed identification pulse are fed to a fan-in circuit which produces the multiplexed output. To demonstrate the method, a prototype 8-to-1 multiplexer was built and ...
