ASA2-20.000MHZ-L-T - ABRACON

ASA2-20.000MHZ-L-T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for this oscillator?
  Abracon recommends a layout with a ground plane underneath the oscillator, and a 10nF capacitor between the output pin and ground to reduce noise and ensure stable operation.
• Can I use this oscillator in a high-temperature environment?
  The ASA2-20.000MHZ-L-T is rated for operation up to 85°C, but Abracon recommends derating the frequency tolerance and stability specifications for temperatures above 70°C. Consult the datasheet for specific derating curves.
• How do I ensure the oscillator starts up reliably in my design?
  Abracon recommends applying a power-up ramp of at least 1ms to ensure reliable startup. Additionally, ensure that the power supply voltage is within the recommended range and that the oscillator is properly decoupled from the power supply.
• What is the equivalent series resistance (ESR) of the internal capacitors?
  The ESR of the internal capacitors is typically around 5 ohms, but this value can vary depending on the specific oscillator configuration and operating conditions. Consult Abracon's application notes for more information.
• Can I use this oscillator in a design with a high level of electromagnetic interference (EMI)?
  The ASA2-20.000MHZ-L-T has a metal lid that provides some shielding against EMI, but Abracon recommends taking additional measures to ensure EMI immunity, such as using a shielded enclosure and proper PCB layout techniques.
