ACH-40.000MHZ-EK 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 reaches the specified operating voltage (1.8V to 3.3V) within 100ms. Additionally, a 10nF to 100nF decoupling capacitor should be placed close to the oscillator.
  • The ACH-40.000MHZ-EK oscillator is rated for operation from -40°C to +85°C. However, Abracon recommends derating the frequency tolerance by ±10ppm for every 10°C above 70°C to ensure reliable operation.
  • No, the ACH-40.000MHZ-EK oscillator is a fixed-frequency device and cannot be adjusted to operate at a different frequency. If a different frequency is required, Abracon offers a range of oscillators with different frequencies, or a custom oscillator can be designed.
  • The typical current consumption of the ACH-40.000MHZ-EK oscillator is around 10mA to 20mA, depending on the specific application and operating conditions. Abracon recommends consulting the datasheet for more detailed information.
