ABS07-32.768KHZ-9 - ABRACON

ABS07-32.768KHZ-9 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical PCB layout with a solid ground plane underneath the oscillator, and keeping the oscillator away from high-frequency noise sources. A 4-layer PCB with a dedicated ground plane 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 maximum operating temperature range for this oscillator?
  The ABS07-32.768KHZ-9 is rated for operation from -40°C to +85°C, but Abracon recommends derating the frequency tolerance by 5ppm/°C for temperatures above 70°C.
• Can I use this oscillator in a high-vibration environment?
  The ABS07-32.768KHZ-9 is designed to withstand vibrations up to 10g, but Abracon recommends additional testing and validation for specific vibration profiles. It's also recommended to use a vibration-dampening material, such as a silicone adhesive, to secure the oscillator to the PCB.
• How do I handle ESD protection for this oscillator?
  Abracon recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the power supply lines and signal lines connected to the oscillator. Additionally, handling the oscillator by the package body instead of the leads can help prevent ESD damage.
