Proper decoupling, bypassing, and power supply noise reduction is important in many applications to ensure optimal performance for oscillators. A common strategy is to place capacitors near high speed devices on a printed circuit board (PCB). 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.
