适当的解耦,旁路和电源降噪在许多应用中是重要的,以确保振荡器的最佳性能。共同的策略是将电容器放置在印刷电路板(PCB)上的高速设备附近。These capacitors serve important functions: Provide instantaneous current to the component Reduce noise propagation through the system Shunt the power supply noise to GND The following sections describe decoupling, bypassing, noise rejection, and power supply condition recommendations for SiTime’s single-ended and differential timing devices.
