Oscillators Procurement Notes

Verify the specific frequency suffix matches the design requirement of 4.6453 MHz. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the PCB footprint accommodates the 4-SMD no-lead package dimensions. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure joint integrity.

Oscillators Selection Notes

Select this component when a precise 4.6453 MHz clock source is required for LVCMOS-compatible circuits. Consider the ±50ppm stability specification against the system's jitter tolerance requirements. Evaluate the enable/disable feature if power conservation during idle states is a critical design constraint. Compare physical size constraints against alternative packages in the same series.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronic. The series offers various frequencies and voltage options, all sharing similar form factors and electrical characteristics. The '-OE' suffix typically denotes specific packaging or ordering configurations defined by the manufacturer. This model represents a specific frequency variant within the broader product line.

Oscillators Replacement Considerations

Direct substitutes must match the 4.6453 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility before swapping. Alternative frequencies in the same package may require firmware adjustments. Consult manufacturer cross-reference lists for verified equivalents.
