Design Recommendations

For stable operation, ensure the load capacitance matches the crystal's CL value. Place a 0.1μF bypass capacitor near the crystal to minimize power supply noise. Keep traces short and symmetrical to reduce stray capacitance and EMI effects, especially in RTC circuits and ultra-low-power systems.
