ASDKDV-32.768KHZ-LR-T - ABRACON

ASDKDV-32.768KHZ-LR-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 to 10 ms, 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 ASDKDV-32.768KHZ-LR-T is rated for operation from -40°C to +85°C. However, Abracon recommends derating the frequency tolerance by 5 ppm/°C for temperatures above 70°C.
• Can I use this oscillator in a high-vibration environment?
  The ASDKDV-32.768KHZ-LR-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 human-body model (HBM) ESD protection device with a minimum rating of 2 kV. Additionally, handling the device by the package rather than the pins can help prevent ESD damage.
