ABS07-32.768KHZ-1 - ABRACON

ABS07-32.768KHZ-1 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 keeping the oscillator away from high-frequency noise sources and digital signals. A minimum of 10mil clearance around the oscillator 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 1ms to 10ms, and a power supply voltage of 1.8V to 3.3V. Additionally, the oscillator should be decoupled with a 10nF to 100nF capacitor.
• What is the operating temperature range for this oscillator?
  The ABS07-32.768KHZ-1 is rated for operation from -40°C to +85°C, but Abracon recommends derating the frequency tolerance by ±0.5ppm/°C for temperatures outside the 0°C to 70°C range.
• Can I use this oscillator in a high-vibration environment?
  The ABS07-32.768KHZ-1 is designed to withstand vibrations up to 10g peak acceleration, but Abracon recommends additional testing and validation for specific vibration profiles and environments.
• How do I handle ESD protection for this oscillator?
  Abracon recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the oscillator's input and output pins to prevent damage from electrostatic discharge.
