Abracon recommends following the recommended PCB layout guidelines in the application note AN-04, which includes keeping the oscillator circuitry away from noise sources, using a solid ground plane, and minimizing trace lengths and widths.
To ensure reliable startup, Abracon recommends using a power-on reset (POR) circuit, ensuring the power supply is stable and within the recommended operating range, and using a capacitor with a suitable value (e.g., 10nF to 100nF) between the VCC and GND pins.
The ASDMB-7.3728MHZ-XC-T has an operating temperature range of -40°C to +85°C, but it's essential to note that the frequency stability and accuracy may degrade at extreme temperatures. Consult the datasheet for specific temperature-related specifications.
While the ASDMB-7.3728MHZ-XC-T is designed to be robust, it's still important to consider the vibration sensitivity of the oscillator. Abracon recommends following the guidelines in the application note AN-05 for designing vibration-resistant oscillator circuits.
Abracon recommends following proper ESD handling procedures during assembly and installation, and considering the use of ESD protection devices (e.g., TVS diodes) in the circuit design to protect the oscillator from electrostatic discharge.
