Abracon recommends a symmetrical layout with the crystal oscillator placed near the center of the PCB, with minimal routing and no vias under the component to minimize noise and signal degradation.
Ensure the power supply voltage is stable and within the recommended range, and add a 10-100nF decoupling capacitor between VCC and GND near the oscillator. Also, verify the oscillator is properly terminated and the load capacitance is within the recommended range.
The ASFLMB-33.000MHZ-LC-T is rated for operation from -40°C to +85°C, but it's recommended to derate the frequency tolerance and stability over the full temperature range.
While the ASFLMB-33.000MHZ-LC-T is designed to be rugged, it's still a sensitive component. For high-vibration or high-shock environments, consider using a more robust oscillator or adding additional mechanical protection, such as potting or conformal coating.
Check the power supply voltage, decoupling, and termination. Verify the load capacitance and ensure the oscillator is properly connected. If issues persist, try replacing the oscillator or consulting the datasheet and application notes for further guidance.
