Modeling Output-to-Output Electromagnetic Crosstalk and Resulting Root Mean Square Jitter in High-Performance Clock Sources [Application Notes]

Timing circuits are ubiquitous in electronic systems, given the need for stable and precise clock signals to synchronize data streams. They typically comprise a phase-locked loop that adjusts the output signal frequency based on a high-Q reference, such as a crystal [1] or bulk acoustic wave resonator. Therefore, timing circuits are essential components for frequency synthesis, clock recovery, and frequency modulation and demodulation with a variety of applications, including high-speed data communications, such as USB, measurement instruments, such as oscilloscopes and network analyzers, and mobile base stations.
