Abracon recommends following a 4-layer PCB stack-up with a solid ground plane on the second layer, and using a 50-ohm microstrip transmission line to connect the crystal to the oscillator circuit. Additionally, keep the crystal away from high-current or high-frequency signals to minimize noise coupling.
To ensure frequency stability, Abracon recommends using a crystal with a tight frequency tolerance (e.g., ±10 ppm) and a high-quality oscillator circuit with a stable voltage supply. Additionally, consider using a temperature-compensated crystal oscillator (TCXO) or an oven-controlled crystal oscillator (OCXO) for more stringent frequency stability requirements.
The maximum drive level for the AX3HAF1-156.2500 is typically around 1-2 μW. Exceeding this level can cause damage or degradation to the crystal. It's essential to follow the recommended drive level and ensure the oscillator circuit is designed to provide a stable and controlled drive signal.
The AX3HAF1-156.2500 is designed to meet the requirements of various industrial and commercial applications, but it may not be suitable for high-vibration or high-shock environments. Abracon recommends consulting their application notes and performing thorough testing to ensure the crystal meets the specific requirements of your application.
Handle the AX3HAF1-156.2500 by the package, avoiding direct contact with the crystal element. Use anti-static wrist straps, mats, or packaging to prevent electrostatic discharge (ESD) damage. During rework, use a low-temperature soldering process (e.g., 200°C) and avoid applying excessive mechanical stress or vibration.
