Abracon recommends a 4-layer PCB with a solid ground plane and a separate power plane for the oscillator. The oscillator should be placed close to the crystal, and the traces should be kept short and shielded to minimize noise and radiation.
To ensure reliable startup, Abracon recommends a power-up ramp time of at least 1 ms/V, and a power supply voltage that is stable and within the recommended operating range. Additionally, the oscillator should be decoupled with a 0.01 uF capacitor and a 10 uF capacitor in parallel.
The ASPI-2010HC-100M-T is rated for operation from -40°C to +85°C, but Abracon recommends derating the frequency by 0.05% per degree Celsius above 70°C to ensure reliable operation.
While the ASPI-2010HC-100M-T is designed to be robust, Abracon recommends taking additional precautions in harsh environments. This may include conformal coating, potting, or using a sealed enclosure to protect the oscillator from moisture and vibration.
Abracon recommends checking the power supply voltage, decoupling, and PCB layout for any issues. Additionally, the oscillator can be tested in a standalone configuration to isolate the problem. If the issue persists, contact Abracon's technical support for further assistance.
