ASA-30.000MHZ-L-T - ABRACON

ASA-30.000MHZ-L-T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the ASA-30.000MHZ-L-T?
  Abracon recommends a symmetrical PCB layout with a ground plane underneath the oscillator, and keeping the traces as short as possible to minimize noise and radiation. A 4-layer PCB with a dedicated ground plane is ideal.
• How do I ensure the oscillator starts up reliably in my design?
  To ensure reliable startup, Abracon recommends a power-up ramp time of at least 1ms, and a power supply voltage that reaches the minimum specified voltage (1.8V) within 100ms. Additionally, a 10nF to 100nF decoupling capacitor should be placed close to the oscillator.
• What is the maximum operating temperature range for the ASA-30.000MHZ-L-T?
  The ASA-30.000MHZ-L-T is rated for operation from -40°C to +85°C. However, Abracon recommends derating the frequency tolerance by 5ppm/°C for temperatures above 70°C.
• Can I use the ASA-30.000MHZ-L-T in a high-vibration environment?
  The ASA-30.000MHZ-L-T is designed to withstand vibrations up to 10g peak acceleration. However, Abracon recommends consulting their application notes for vibration-sensitive designs, and considering the use of vibration-dampening materials or mounting techniques.
• How do I handle ESD protection for the ASA-30.000MHZ-L-T?
  Abracon recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the power supply lines and signal lines connected to the oscillator. Additionally, handling the device by the package rather than the pins can help prevent ESD damage.
