ASPI-0315FS-470M-T2 - ABRACON

ASPI-0315FS-470M-T2 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 in my design?
  To ensure reliable startup, Abracon recommends a power-up ramp time of at least 1 ms/V, and a power supply voltage that reaches the minimum specified voltage (1.8V) within 10 ms. Additionally, ensure the oscillator is not loaded with excessive capacitance during startup.
• What is the maximum allowable capacitance load for this oscillator?
  The maximum allowable capacitance load for the ASPI-0315FS-470M-T2 is 15 pF. Exceeding this limit may affect the oscillator's frequency stability and startup reliability.
• Can I use this oscillator in a high-temperature environment?
  The ASPI-0315FS-470M-T2 is rated for operation up to 125°C. However, the frequency stability and accuracy may degrade at higher temperatures. Consult Abracon's application note AN-05 for guidance on using crystal oscillators in high-temperature environments.
• 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. Ensure the ESD protection device is rated for the oscillator's operating voltage and frequency.
