ASFLMPC-27.000MHZ-Z-T - ABRACON

ASFLMPC-27.000MHZ-Z-T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical layout with the crystal oscillator placed near the center of the PCB, with minimal routing and no vias under the component. A ground plane underneath the component is also 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 1-2 ms, and a power supply voltage that is stable and within the recommended operating range. Additionally, a 10-100 nF decoupling capacitor should be placed close to the oscillator.
• What is the maximum allowable frequency deviation for this oscillator?
  The ASFLMPC-27.000MHZ-Z-T has a frequency tolerance of ±20 ppm over the operating temperature range. This means the oscillator's frequency can deviate by up to 540 Hz from the nominal 27.000 MHz frequency.
• Can I use this oscillator in a harsh environment?
  The ASFLMPC-27.000MHZ-Z-T is rated for operation in the industrial temperature range of -40°C to +85°C. However, it's essential to ensure the oscillator is properly soldered and the PCB is designed to withstand the environmental conditions.
• What is the recommended drive level for this oscillator?
  Abracon recommends a drive level of 1-5 pF for the ASFLMPC-27.000MHZ-Z-T. This ensures reliable startup and stable operation.
