ASEM1-3.500MHZ-EC-T Frequently Asked Questions (FAQs)

  • Abracon recommends a layout with a ground plane underneath the oscillator, and keeping the traces as short as possible to minimize parasitic inductance and capacitance. A 4-layer PCB with a dedicated ground plane is ideal.
  • The ASEM1-3.500MHZ-EC-T is rated for operation up to 85°C, but its frequency stability may degrade at higher temperatures. Abracon recommends derating the frequency tolerance by 5 ppm/°C above 70°C.
  • Yes, the ASEM1-3.500MHZ-EC-T is designed to minimize EMI emissions. Abracon recommends using a shielded enclosure and following good PCB design practices to further reduce EMI.
  • Abracon recommends a drive level of 1-10 μW to ensure reliable operation and minimize power consumption.
  • The ASEM1-3.500MHZ-EC-T oscillator is designed to exhibit minimal aging effects, with a frequency drift of less than 5 ppm over 10 years at 25°C.
