FSR327 datasheet by Fox Electronics

FSR327 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for FSR327?
  Fox Electronics recommends a PCB layout with a minimum of 0.5mm clearance around the component and a land pattern with a 1.5mm diameter pad for the oscillator pin and 0.8mm diameter pads for the other pins.
• How do I ensure the FSR327 oscillator starts reliably?
  To ensure reliable oscillator startup, Fox Electronics recommends a 10kΩ to 22kΩ pull-up resistor on the oscillator pin, a 10nF to 22nF capacitor between the oscillator pin and ground, and a 1kΩ to 2kΩ series resistor on the oscillator pin.
• What is the maximum operating temperature range for FSR327?
  The FSR327 can operate safely within a temperature range of -40°C to +85°C, but Fox Electronics recommends derating the frequency by 0.05% per °C above 70°C to ensure optimal performance.
• Can I use the FSR327 in a high-vibration environment?
  Yes, the FSR327 is designed to withstand high-vibration environments. However, Fox Electronics recommends following proper PCB mounting and soldering techniques to ensure the component remains securely attached to the board.
• How do I troubleshoot FSR327 oscillator failure?
  To troubleshoot oscillator failure, check for proper PCB layout and component placement, ensure the oscillator pin is not loaded with excessive capacitance, and verify the power supply voltage is within the recommended range. If issues persist, consult Fox Electronics' application notes or contact their technical support.
