FOXLF040 - Fox

FOXLF040 Frequently Asked Questions (FAQs)

• What is the recommended power supply decoupling for the FOXLF040?
  Fox Electronics recommends using a 0.1uF ceramic capacitor in parallel with a 10uF electrolytic capacitor, placed as close as possible to the VCC pin, to ensure stable operation.
• How do I ensure the FOXLF040 oscillator starts up reliably?
  To ensure reliable startup, Fox Electronics recommends applying power to the VCC pin slowly, with a rise time of at least 1ms, and ensuring that the voltage supply is stable before enabling the oscillator.
• What is the maximum frequency deviation of the FOXLF040 over temperature?
  The FOXLF040 has a maximum frequency deviation of ±100ppm over the operating temperature range of -40°C to +85°C.
• Can I use the FOXLF040 in a noisy environment?
  Yes, the FOXLF040 has a high immunity to electromagnetic interference (EMI) and can operate reliably in noisy environments. However, it's still recommended to follow proper PCB design and layout practices to minimize noise coupling.
• How do I adjust the output frequency of the FOXLF040?
  The output frequency of the FOXLF040 can be adjusted by connecting a resistor (R1) between the FREQ_ADJ pin and GND. The frequency adjustment range is ±5% of the nominal frequency.
