ASD3-20.000MHZ-EC-T Details

Abracon recommends a layout with a ground plane underneath the oscillator, and to keep the traces as short as possible to minimize parasitic inductance and capacitance. A 4-layer PCB with a dedicated ground layer is also recommended.
The ASD3-20.000MHZ-EC-T is rated for operation up to 85°C, but its frequency stability may degrade at higher temperatures. Abracon recommends derating the oscillator's frequency tolerance by 5 ppm/°C above 70°C.
Yes, the ASD3-20.000MHZ-EC-T has a built-in EMI filter that helps reduce electromagnetic interference. However, additional EMI mitigation techniques such as shielding, grounding, and layout optimization may still be necessary to meet specific EMI requirements.
Abracon recommends a drive level of 1-10 μW to ensure optimal performance and minimize power consumption. Excessive drive levels can lead to oscillator degradation or failure.
The ASD3-20.000MHZ-EC-T oscillator is designed to exhibit minimal aging and frequency drift over time. Abracon specifies a maximum frequency drift of ±5 ppm over 10 years at 25°C. However, actual performance may vary depending on environmental conditions and usage.
