ASV-20.000MHZ-LR-T - ABRACON

ASV-20.000MHZ-LR-T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical PCB layout with a solid ground plane, and to keep the oscillator away from high-frequency noise sources. A minimum of 2-layer PCB is recommended, with the oscillator on the top layer and the ground plane on the bottom layer.
• How do I handle the oscillator's output signal in my design?
  The ASV-20.000MHZ-LR-T has a CMOS output stage, which can drive a load of up to 15pF. It's recommended to use a series resistor (e.g. 1kΩ) to limit the output current and prevent damage to the oscillator or downstream components.
• What is the operating temperature range for this oscillator?
  The ASV-20.000MHZ-LR-T is specified to operate from -40°C to +85°C, but it's recommended to derate the frequency tolerance and stability over temperature according to the datasheet.
• Can I use this oscillator in a high-vibration or high-shock environment?
  The ASV-20.000MHZ-LR-T is designed to meet the requirements of MIL-STD-883, Method 2002.5 for vibration and MIL-STD-883, Method 2001.7 for shock. However, it's recommended to consult with Abracon's application engineers for specific guidance on using the oscillator in harsh environments.
• How do I ensure the oscillator's frequency accuracy and stability over time?
  Abracon recommends using a crystal oscillator with a high-quality crystal resonator, such as the ASV-20.000MHZ-LR-T, and following proper PCB design and layout guidelines. Additionally, the oscillator should be stored and operated within the specified temperature range, and protected from environmental stressors such as humidity and radiation.
