FPXLF100-20 datasheet by Fox Electronics

FPXLF100-20 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A good PCB layout for the FPXLF100-20 involves keeping the oscillator as close to the crystal as possible, using a ground plane under the oscillator, and minimizing trace lengths and widths to reduce noise and EMI.
• How do I ensure the oscillator starts up reliably?
  To ensure reliable startup, make sure the power supply is stable and within the recommended voltage range, and that the oscillator is properly decoupled with a 10nF to 100nF capacitor between VCC and GND.
• What is the maximum frequency deviation over temperature?
  The FPXLF100-20 has a maximum frequency deviation of ±100 ppm over the operating temperature range of -40°C to +85°C.
• Can I use the FPXLF100-20 in a high-vibration environment?
  Yes, the FPXLF100-20 is designed to operate in high-vibration environments, but it's essential to ensure the oscillator is properly mounted and secured to the PCB to prevent mechanical stress.
• How do I troubleshoot issues with the oscillator not oscillating?
  To troubleshoot, check the power supply voltage, ensure the crystal is properly connected, and verify that the oscillator is properly decoupled. Also, check for any signs of damage or contamination on the oscillator or PCB.
