FSMLF327 Frequently Asked Questions (FAQs)

  • A symmetrical layout with the oscillator at the center, using a ground plane, and keeping the output traces short and matched is recommended for optimal performance and minimal jitter.
  • Ensure the power supply is stable and has a low ripple, and add a 10-100nF capacitor between VCC and GND to filter out noise. Also, ensure the output is not loaded during startup.
  • The frequency deviation due to temperature changes is typically ±100 ppm over the operating temperature range of -40°C to 85°C.
  • Yes, but ensure the total capacitive load does not exceed 15pF, and consider using a buffer or repeater if the load is too high or the distance is too great.
  • Check the power supply, ensure the output is not loaded, and verify the PCB layout is correct. Also, check for any noise or interference on the power or output lines.
