AMPMGFB-19.2000T - ABRACON

AMPMGFB-19.2000T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical PCB layout with a solid ground plane to minimize noise and radiation. A minimum of 2-3 vias under the device is recommended to connect the ground plane to the internal ground of the device.
• How do I ensure the oscillator starts up reliably?
  To ensure reliable startup, Abracon recommends a power-up ramp time of at least 1ms/V, and a power supply voltage that is within the recommended operating range. Additionally, the oscillator circuit should be decoupled from the power supply with a 10nF to 100nF capacitor.
• What is the maximum operating temperature range for this device?
  The AMPMGFB-19.2000T is rated for operation from -40°C to +85°C. However, Abracon recommends derating the frequency by 0.05% per degree Celsius above 70°C to ensure reliable operation.
• Can I use this device in a high-vibration environment?
  Yes, the AMPMGFB-19.2000T is designed to withstand vibrations up to 10g peak acceleration. However, Abracon recommends following proper PCB mounting and soldering techniques to ensure the device is securely attached to the board.
• How do I troubleshoot issues with the oscillator not starting?
  Abracon recommends checking the power supply voltage, ensuring the oscillator circuit is properly decoupled, and verifying the PCB layout meets the recommended guidelines. Additionally, checking for any damage to the device or PCB can help identify the root cause of the issue.
