LFSPXO019987 - IQD

LFSPXO019987 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  IQD Frequency Products recommends a 4-layer PCB with a solid ground plane, and the oscillator should be placed as close as possible to the microcontroller or ASIC. A minimum of 10mm clearance around the oscillator is recommended to minimize electromagnetic interference.
• How do I ensure the oscillator starts up correctly in my application?
  To ensure the oscillator starts up correctly, IQD Frequency Products recommends applying power to the VCC pin before the enable pin (EN). The enable pin should be pulled high or connected to VCC to enable the oscillator. A 10kΩ pull-up resistor is recommended on the enable pin if it's not driven by a logic signal.
• What is the maximum operating temperature range for this oscillator?
  The LFSPXO019987 has an operating temperature range of -40°C to +85°C. However, IQD Frequency Products recommends derating the frequency stability and aging specifications for temperatures above +70°C.
• Can I use this oscillator in a harsh environment with high vibration or shock?
  The LFSPXO019987 is designed to meet the requirements of MIL-STD-883, Method 2002.3 for vibration and MIL-STD-883, Method 2001.3 for shock. However, IQD Frequency Products recommends consulting with their application engineers to ensure the oscillator meets the specific requirements of your application.
• What is the recommended soldering profile for this oscillator?
  IQD Frequency Products recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a ramp rate of 3°C/second. The oscillator should be handled with care to avoid mechanical stress during the soldering process.
