IQD Frequency Products recommends a ground plane underneath the oscillator, with a minimum of 2mm clearance around the device. A 4-layer PCB with a dedicated ground layer is also recommended to minimize noise and EMI.
To ensure proper startup, IQD recommends applying power to the VCC pin before enabling the oscillator. A soft-start circuit can also be used to prevent inrush currents and ensure a stable startup.
While the datasheet specifies an operating temperature range of -40°C to +85°C, IQD Frequency Products recommends derating the oscillator's frequency stability and output amplitude above 70°C to ensure reliable operation.
Yes, the LFSPXO009682 is designed to withstand vibrations up to 10g peak acceleration. However, IQD recommends ensuring the oscillator is properly secured to the PCB and that the PCB is rigid enough to minimize vibration-induced stress.
IQD recommends checking the power supply voltage, ensuring the oscillator is properly terminated, and verifying the load capacitance. If issues persist, contact IQD's technical support for further assistance.
