A good PCB layout for the FOX924B-27.000 involves keeping the input and output traces as short as possible, using a solid ground plane, and minimizing the distance between the crystal and the oscillator pins.
To ensure reliable startup, make sure the power supply is stable, the crystal is properly mounted, and the oscillator pins are not loaded with excessive capacitance. Also, ensure the oscillator is not subjected to excessive noise or EMI.
The maximum allowable frequency deviation for the FOX924B-27.000 is typically ±50 ppm over the operating temperature range. However, this may vary depending on the specific application and requirements.
The FOX924B-27.000 is rated for commercial temperature range (0°C to 70°C). For harsh environments, consider using a more ruggedized oscillator or taking additional measures to ensure reliable operation, such as using a temperature-controlled environment or adding thermal protection.
To troubleshoot issues, check the power supply, crystal, and PCB layout. Verify that the oscillator is properly connected and not subjected to excessive noise or EMI. Use an oscilloscope to verify the oscillator output and check for any signs of instability or jitter.
