LFXTAL085878 - IQD

LFXTAL085878 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  IQD Frequency Products recommends a symmetrical PCB layout with a ground plane underneath the oscillator to minimize noise and radiation. A minimum of 10mm clearance around the device is also recommended.
• How do I ensure the oscillator starts up reliably in my design?
  To ensure reliable startup, IQD recommends a power-up ramp time of at least 1ms, and a power supply voltage that reaches the minimum specified voltage (1.8V) within 10ms of power-up.
• What is the maximum allowable frequency deviation due to temperature changes?
  The LFXTAL085878 has a specified frequency deviation of ±20 ppm over the operating temperature range of -40°C to +85°C. This means that the frequency can deviate by up to 20 parts per million from the nominal frequency due to temperature changes.
• Can I use this oscillator in a high-vibration environment?
  The LFXTAL085878 is designed to withstand vibrations up to 10g peak acceleration, making it suitable for use in environments with moderate vibration levels. However, it's recommended to consult IQD Frequency Products for specific vibration testing and validation.
• What is the recommended soldering profile for this device?
  IQD Frequency Products recommends a soldering profile with a peak temperature of 260°C, a dwell time above 220°C of 30-60 seconds, and a total process time of less than 300 seconds.
