Abracon recommends a symmetrical PCB layout with a solid ground plane, and the crystal oscillator should be placed as close as possible to the microcontroller or IC. A minimum of 10 mils (0.25 mm) clearance around the device is recommended.
Abracon recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the PCB to protect the crystal oscillator from electrostatic discharge. Additionally, handling the device with an anti-static wrist strap or mat can prevent ESD damage.
The ASEMB-40.000MHZ-LC-T is rated for operation from -40°C to +85°C. However, it's essential to note that the frequency tolerance and stability may vary outside the recommended operating temperature range.
While the ASEMB-40.000MHZ-LC-T is designed to be rugged, it's still susceptible to vibration-induced frequency shifts. Abracon recommends using vibration-dampening materials or mounting the device on a rigid PCB to minimize the effects of vibration.
Abracon offers custom frequency tolerance options for the ASEMB-40.000MHZ-LC-T. Engineers should contact Abracon's sales team or authorized distributors to discuss their specific requirements and obtain a custom part number.
