Design Recommendations
Ensure proper board mounting of both leads to avoid mechanical stress. Match the circuit’s load capacitance with the crystal’s specification to ensure optimal timing performance. Position a 0.1μF capacitor close to the circuit to minimize power supply noise. Avoid routing high-speed or noisy signals near the crystal path to prevent timing instability.
