FSRLF327 Frequently Asked Questions (FAQs)

  • A symmetrical layout with a solid ground plane and minimal signal trace length is recommended. Keep the oscillator away from noise sources and ensure a low-impedance path to ground.
  • Ensure a clean power supply, add a 10-100nF decoupling capacitor between VCC and GND, and use a pull-up resistor (1kΩ-10kΩ) on the EN pin to prevent unwanted startup.
  • The frequency deviation is typically ±100 ppm over the operating temperature range (-40°C to 85°C). For more accurate applications, consider using a temperature-compensated oscillator.
  • Yes, but take precautions to minimize electromagnetic interference (EMI). Use shielding, keep the oscillator away from noise sources, and ensure a low-impedance path to ground.
  • The output frequency can be adjusted by connecting a resistor (R1) between the FREQ_ADJ pin and GND. The frequency adjustment range is approximately ±5%.
