ASFL1-32.768MHZ-L-T - ABRACON

ASFL1-32.768MHZ-L-T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical PCB layout with a ground plane underneath the oscillator to minimize noise and radiation. A minimum of 10 mil clearance around the device is recommended.
• How do I ensure the oscillator starts up reliably in my design?
  To ensure reliable startup, Abracon recommends a power-up ramp time of 1 ms or slower, and a power supply voltage of 1.8V to 3.3V. Additionally, a 10 kΩ to 100 kΩ pull-up resistor on the output pin can help stabilize the oscillator.
• What is the maximum operating temperature range for this oscillator?
  The ASFL1-32.768MHZ-L-T is rated for operation from -40°C to +85°C. However, Abracon recommends derating the frequency tolerance by ±5 ppm for every 10°C above 70°C.
• Can I use this oscillator in a high-vibration environment?
  The ASFL1-32.768MHZ-L-T is designed to withstand vibrations up to 10 G peak acceleration. However, Abracon recommends consulting their application notes for vibration-sensitive designs and considering additional mechanical support or damping measures.
• How do I handle ESD protection for this oscillator?
  Abracon recommends using a TVS diode or ESD protection device on the power supply lines and I/O pins to prevent damage from electrostatic discharge. A minimum of 2 kV HBM and 100 V MM protection is recommended.
