Fox Electronics recommends a symmetrical PCB layout with the oscillator placed near the center of the board, and the output traces should be kept short and matched to minimize signal reflections.
To ensure reliable startup, Fox Electronics recommends applying power to the oscillator slowly (dv/dt < 10V/ms) and ensuring that the power supply is stable and noise-free. Additionally, a 10nF to 100nF capacitor can be placed between the VCC and GND pins to filter out noise.
While the datasheet specifies an operating temperature range of -40°C to +85°C, Fox Electronics recommends derating the oscillator's frequency by 0.005% per °C above 70°C to ensure reliable operation.
Yes, the FPX080 is designed to operate in high-vibration environments. However, Fox Electronics recommends ensuring that the oscillator is properly secured to the PCB and that the PCB is designed to withstand the expected vibration levels.
To troubleshoot frequency accuracy issues, Fox Electronics recommends checking the power supply voltage, ensuring that the oscillator is properly terminated, and verifying that the PCB layout is symmetrical and free from noise sources. Additionally, a frequency counter or spectrum analyzer can be used to measure the oscillator's frequency.
