Oscillators Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's official datasheet before procurement. Confirm that the 4-SMD footprint matches the target PCB layout dimensions. Ensure the supply voltage requirements align with the system's power rail specifications. Cross-reference the part number with authorized distributors to guarantee authenticity and traceability. Check for any recent product lifecycle changes or obsolescence notices from ILSI.

Oscillators Selection Notes

Select this component when a 19.44 MHz TCXO is required for applications demanding superior frequency stability compared to standard crystal oscillators. Consider the 4-SMD package size constraints during the mechanical design phase. Evaluate the clipped sine wave output compatibility with downstream circuitry. Assess the thermal management requirements based on the expected operating temperature range. Compare performance metrics against alternative frequencies if the exact 19.44 MHz specification is not strictly mandatory.

Oscillators Part Context

This oscillator belongs to the ILSI I547 series, which offers various frequency options within the same physical package and electrical interface. The series is characterized by its compact form factor and robust temperature compensation capabilities. Other variants in this family include different nominal frequencies such as 12.8 MHz, 13 MHz, 16 MHz, 20 MHz, and 32 MHz, all sharing similar mounting and voltage characteristics.

Oscillators Replacement Considerations

Direct replacements must match the 19.44 MHz frequency, 3.3V supply, and 4-SMD package. Verify pinout compatibility and output waveform specifications. Consult ILSI documentation for approved cross-references or newer revisions of the I547 series.
