Abracon recommends a symmetrical PCB layout with a solid ground plane, and the oscillator should be placed as close as possible to the microcontroller or IC. A minimum of 10 mils (0.25 mm) clearance around the oscillator is recommended to minimize noise and interference.
Abracon recommends following standard ESD handling procedures, such as using an ESD wrist strap or mat, and storing the components in anti-static packaging. The ASFLMB-4.000MHZ-LR-T has an internal ESD protection diode, but external protection measures are still necessary to prevent damage.
The ASFLMB-4.000MHZ-LR-T has an operating temperature range of -40°C to +85°C, but it's recommended to operate within the -20°C to +70°C range for optimal performance and reliability.
The ASFLMB-4.000MHZ-LR-T is designed to withstand moderate vibration levels, but it's not recommended for high-vibration environments. If you need an oscillator for a high-vibration application, consider Abracon's vibration-resistant oscillators or consult with their technical support team.
The recommended load capacitance for the ASFLMB-4.000MHZ-LR-T is 18 pF. However, the optimal load capacitance may vary depending on the specific application and PCB layout. Consult Abracon's application notes or contact their technical support team for guidance on determining the correct load capacitance.
