ASEM1-27.000MHZ-LC-T Frequently Asked Questions (FAQs)

  • Abracon recommends a soldering temperature profile with a peak temperature of 240°C to 250°C, with a dwell time of 1-2 seconds. This ensures reliable solder joints and minimizes thermal stress on the component.
  • The ASEM1-27.000MHZ-LC-T oscillator is designed to handle power-up and power-down sequences without any specific requirements. However, it's recommended to ensure a monotonic power supply ramp-up and ramp-down to prevent any potential oscillation or frequency instability issues.
  • Abracon recommends a PCB layout with a dedicated ground plane and a land pattern that follows the JEDEC standard for QFN packages. A minimum of 2mm clearance around the component is recommended to ensure proper heat dissipation and to prevent electrical interference.
  • The ASEM1-27.000MHZ-LC-T oscillator is rated for operation up to 85°C. While it can tolerate short-term excursions up to 100°C, prolonged exposure to high temperatures may affect its long-term reliability and frequency stability. For high-temperature applications, Abracon recommends using a more suitable oscillator or consulting with their application engineers.
  • The ASEM1-27.000MHZ-LC-T oscillator is designed to be resistant to EMI, but it's still important to follow proper PCB layout and shielding practices to minimize the impact of EMI on the oscillator's performance. Abracon recommends using a shielded enclosure and following good electromagnetic compatibility (EMC) design practices.
