ASEM1-40.000MHZ-LC-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.
  • To ensure reliable startup, Abracon recommends a power-up ramp time of at least 1ms, and a power supply voltage that meets the specified operating range. Additionally, the oscillator should be decoupled from the power supply with a 10nF to 100nF capacitor.
  • The ASEM1-40.000MHZ-LC-T oscillator is rated for operation from -40°C to +85°C. However, Abracon recommends derating the frequency tolerance and stability specifications for operation above +70°C.
  • No, the ASEM1-40.000MHZ-LC-T oscillator is a fixed-frequency device and cannot be adjusted to operate at a different frequency. Abracon offers a range of frequencies in their ASEM1 series, so it's recommended to select the correct part number for the desired frequency.
  • The typical current consumption of the ASEM1-40.000MHZ-LC-T oscillator is around 10mA to 20mA, depending on the load capacitance and operating conditions. However, the maximum current consumption is specified as 30mA in the datasheet.
