ABL-8.000MHZ-B2-T - ABRACON

ABL-8.000MHZ-B2-T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the ABL-8.000MHZ-B2-T crystal oscillator?
  Abracon recommends a layout with a ground plane underneath the oscillator, and to keep the traces as short as possible to minimize parasitic inductance and capacitance. A 4-layer PCB with a dedicated ground layer is also recommended.
• How does the ABL-8.000MHZ-B2-T oscillator behave in high-temperature environments?
  The ABL-8.000MHZ-B2-T is rated for operation up to 125°C, but its frequency stability may degrade at higher temperatures. Abracon recommends derating the frequency tolerance by 5 ppm/°C above 85°C.
• Can the ABL-8.000MHZ-B2-T be used in a design that requires a specific EMI reduction?
  Yes, the ABL-8.000MHZ-B2-T has a built-in EMI filter that helps reduce electromagnetic interference. However, additional EMI mitigation techniques such as shielding, grounding, and layout optimization may still be necessary to meet specific EMI requirements.
• What is the recommended drive level for the ABL-8.000MHZ-B2-T oscillator?
  Abracon recommends a drive level of 1-10 μW to ensure optimal performance and minimize power consumption. Higher drive levels may cause the oscillator to operate outside its specified frequency range.
• How does the ABL-8.000MHZ-B2-T oscillator perform in terms of aging and frequency drift over time?
  The ABL-8.000MHZ-B2-T has a typical aging rate of ±5 ppm/year, and its frequency drift is typically ±10 ppm over a 10-year period. However, these values can vary depending on environmental factors and operating conditions.
