• Digital communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm the 1.8V operating voltage requirement. Ensure the selected variant matches the required frequency tolerance and package dimensions for your PCB footprint. Cross-reference the manufacturer's part number directly with authorized distributors to avoid counterfeit components. Confirm that the enable pin configuration aligns with your system's power management strategy before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and precise 4 MHz timing is required. Consider the ±20 ppm stability for general-purpose applications rather than high-precision RF systems. Evaluate the 30 mA current consumption against total system power budgets. The CMOS output is suitable for direct connection to standard logic inputs without additional buffering in most cases.

Oscillators Part Context

This oscillator belongs to the SX3M series, which offers various voltage options including 1.2V, 1.8V, 2.5V, and 3.3V variants. The series provides different stability grades and frequency ranges within a standardized 3.2mm x 2.5mm SMD package. This specific model targets applications requiring lower voltage operation compared to the standard 3.3V versions found in the same product family.

Oscillators Replacement Considerations

Direct substitutes may include other 4MHz CMOS oscillators with identical 1.8V supply requirements and ±20 ppm stability. Verify pinout compatibility and package dimensions before swapping. Alternative models from the same manufacturer with different voltage suffixes are not electrically compatible without circuit modification.
