Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency option required during ordering, as the part number suffix may denote the selected output frequency variant. Confirm that the 4-SMD package footprint matches the target PCB layout. Ensure the supply voltage on the design board remains within the 1.71V to 3.63V operational window to guarantee correct oscillator function and stability specifications.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when a small form factor and low current draw are critical constraints. The MEMS construction offers superior reliability compared to traditional quartz crystals in high-vibration environments. Consider the ±50ppm stability limit for applications where tighter tolerance is not required, balancing cost and performance needs effectively.

Pin ConfigurableSelectable Oscillators Part Context

This oscillator belongs to the AMPD series of configurable MEMS devices from Abracon. These components replace discrete crystal resonators and driver circuits with a single integrated solution. The series emphasizes miniaturization and configurability, allowing designers to adjust frequency settings without changing the physical component package or redesigning the circuit board.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct substitutes include other Abracon AMPD series variants such as AMPDEEH-A04 or AMPDEFH-A04, provided the pinout and package dimensions remain compatible. Cross-manufacturer replacements require careful verification of the CMOS output voltage levels, supply current limits, and mechanical footprint to ensure functional equivalence.
