Fox Electronics recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the oscillator circuit. Additionally, keep the oscillator circuit away from noisy digital signals and ensure a low-impedance path for the crystal oscillator.
To ensure reliable startup, Fox Electronics recommends a power-up ramp time of at least 1ms, and a power supply voltage that reaches the minimum specified voltage (1.8V) before the oscillator is enabled. Additionally, ensure the crystal oscillator circuit is properly biased and the load capacitors are correctly selected.
The maximum allowable frequency deviation for the FQ7050B-6.000 is ±50 ppm over the operating temperature range of -40°C to +85°C. This deviation includes initial frequency tolerance, temperature stability, and aging effects.
Yes, the FQ7050B-6.000 can be used in designs that require a different output frequency. However, this may require additional external components, such as a frequency divider or multiplier, and may affect the overall performance and accuracy of the oscillator.
Fox Electronics recommends storing the FQ7050B-6.000 in a dry, cool place, away from direct sunlight and moisture. The storage temperature should be between -40°C and +85°C, and the relative humidity should be below 80%. Avoid exposing the device to mechanical stress, vibration, or electrical overstress.
