To many engineers, clock selection involves nothing more than identifying a clock that will generate the necessary frequency or frequencies/output format, including it in the design, and moving on.

Multiple, independent clocks are ubiquitous in system-on-chip (SoC) design. Most SoC devices have multiple interfaces, some following standards that use very different clock frequencies. Many modern ...

Today's leading-edge system-on-chip (SoC) designs typically have multiple clock domains and, in many cases, multiple internally generated clocks. In test mode, those clocks may be combined into one, ...
