Abracon recommends a symmetrical layout with the crystal oscillator placed close to the microcontroller, and using a ground plane to minimize noise and radiation.
The ASFLMB-16.384MHZ-LR-T requires a CMOS-compatible drive level. Ensure the driving circuitry can provide a minimum of 1.65V peak-to-peak voltage swing to guarantee proper oscillation.
Store the device in a dry, cool place, away from direct sunlight and moisture. The recommended storage temperature range is -40°C to 85°C.
While the ASFLMB-16.384MHZ-LR-T is designed to be robust, it's essential to ensure the device is properly mounted and secured to withstand vibrations. Consult Abracon's application notes for guidance on vibration-resistant design.
Check the PCB layout, ensure proper power supply decoupling, and verify the driving circuitry meets the recommended specifications. If issues persist, consult Abracon's technical support or application notes for further guidance.
