ASPI-8040S-430M-T - ABRACON

ASPI-8040S-430M-T 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 to keep the oscillator away from high-frequency noise sources. A 4-layer PCB with a dedicated ground plane is ideal. Refer to Abracon's application note AN-04 for more details.
• How do I ensure the oscillator starts up reliably?
  To ensure reliable startup, Abracon recommends a power supply ramp-up time of 1ms or slower, and a power supply voltage of at least 1.8V. Additionally, the oscillator should be decoupled with a 0.01uF capacitor between VCC and GND.
• What is the operating temperature range for this oscillator?
  The ASPI-8040S-430M-T has an operating temperature range of -40°C to +85°C. However, it's essential to note that the frequency stability and accuracy may degrade at extreme temperatures.
• Can I use this oscillator in a high-vibration environment?
  The ASPI-8040S-430M-T is designed to withstand vibrations up to 20G. However, it's crucial to ensure the oscillator is properly mounted and secured to the PCB to prevent damage or detuning.
• How do I handle ESD protection for this oscillator?
  Abracon recommends using ESD protection devices, such as TVS diodes or ESD arrays, to protect the oscillator from electrostatic discharge. The protection devices should be placed as close as possible to the oscillator.
