Bulletproof Your System Timing With Programmable Clocks

Ever wondered how much timing margin your system really has? You’ve probably asked some questions along these lines, such as: Does my crystal really need 20 parts-per-million (ppm) accuracy? What if ...

System Clock Generators: A Comparison of a PLL Synthesizer vs. a Crystal Oscillator Clock

An electronic system requires a reliable, precision timing reference: the system clock. We examine and compare two forms of system clocks, the Crystal Oscillator and the Phase Locked Loop Synthesizer ...

Knowledge of clocking aids ASIC-emulator choice

Originally, ASIC emulators used simple clocking—the target system supplied it. However, as custom-processor-based emulators emerged and manufacturers added multiplexed I/O capabilities to increase the ...
