LFXTAL059585 - IQD

LFXTAL059585 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  IQD Frequency Products recommends a symmetrical PCB layout with a solid ground plane underneath the oscillator to minimize noise and radiation. The oscillator should be placed away from high-frequency components and traces.
• 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. Additionally, the oscillator should be decoupled with a 10nF capacitor between VCC and GND.
• What is the maximum operating temperature range for this oscillator?
  The LFXTAL059585 is rated for operation from -40°C to +85°C. However, IQD recommends derating the frequency tolerance by ±5ppm for every 10°C above 70°C to ensure reliable operation.
• Can I use this oscillator in a high-vibration environment?
  The LFXTAL059585 is designed to withstand vibrations up to 10g peak acceleration, but IQD recommends additional testing and validation for specific vibration profiles to ensure reliable operation.
• How do I handle ESD protection for this oscillator?
  IQD recommends using a TVS diode or ESD protection device with a capacitance of ≤10pF to protect the oscillator from electrostatic discharge. The protection device should be connected between the oscillator's input pins and GND.
