The crystal oscillator may also disturb other signals and cause EMI noise. • The load capacitors, crystal and parallel resistors should be placed close to each other. ... WebJun 2, 2024 · The oscillator is recommended to use a specific circuit layout. This is a very small circuit. Follow the data sheet. An adjacent ground plane would introduce much C to ground. It's likely that the oscillator requires certain ratios of capacitance, and maximum capacitance to function properly, hence their recommendation.
