WebJun 21, 2024 · Oscillator Printed Circuit Board (PCB) Design Guidelines • Layout the oscillator footprint on the PCB as close as possible to the input pins of the load or chip. • The length of traces should be as short as possible and must not cross other signal lines. • Avoid right angle bends on traces. WebThe crystal oscillator and its resistors and capacitors must be placed within 12mm (approx. 500mils) of the PHY. The power supply decoupling capacitors need to be placed within 7mm (approx. 280mils) of the power supply.

WebHowever, in real system design, it is not practicable to copy the EV kit PCB exactly. Therefore, a trade-off needs be considered between clock accuracy, PCB stackup and … WebJun 14, 2024 · Crystal oscillator signals are quite weak and need to be protected from interference. When laying out clock/oscillator signals: Make sure the crystal load capacitors are according to the crystal datasheet. Load capacitors for the crystal must be located close to the crystal itself.
Webdeformation of the crystal will cause a voltage across the terminals. Once the oscillator has started, the changing voltage on the termi-nals of the vibrating crystal is used as the clock signal.
