ABMM2-14.7456MHZ-D1-T - ABRACON

ABMM2-14.7456MHZ-D1-T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical layout with a solid ground plane, and keeping the oscillator as close to the microcontroller as possible. A 4-layer PCB with a dedicated ground plane is ideal. Avoid routing signals under the oscillator.
• How do I ensure the oscillator starts up reliably in my design?
  Ensure the power supply is stable and within the recommended voltage range. Add a 10-100nF decoupling capacitor between VCC and GND near the oscillator. Avoid using a capacitor with high ESR. Verify the oscillator is properly terminated with a 1kΩ to 10kΩ resistor.
• What is the maximum frequency deviation I can expect over temperature?
  The ABMM2-14.7456MHZ-D1-T has a frequency stability of ±20 ppm over the operating temperature range of -40°C to 85°C. This means the frequency can deviate by up to ±294 Hz over the entire temperature range.
• Can I use this oscillator in a high-vibration environment?
  The ABMM2-14.7456MHZ-D1-T is designed to withstand moderate vibration. However, for high-vibration environments, Abracon recommends using a more ruggedized oscillator or taking additional measures to secure the component, such as using a vibration-dampening material or a more robust PCB design.
• What is the recommended storage condition for the oscillator?
  Store the oscillator in a dry, cool place, away from direct sunlight and moisture. Avoid exposing the device to temperatures above 85°C or below -40°C. Keep the device in its original packaging or a similar ESD-protective package to prevent damage.
