Oscillators Procurement Notes

Verify the specific frequency suffix matches the required system timing specification before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the PCB footprint accommodates the 2.0x1.6mm SMD package dimensions. Check availability status as inventory levels may fluctuate rapidly.

Oscillators Selection Notes

Select this component when a precise 16.25 MHz clock source is required for low-voltage digital circuits. Consider the ±50ppm stability requirement against the system's jitter tolerance. Evaluate the enable pin functionality if power conservation during idle states is a design priority. Compare package size constraints against available board real estate.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronics. The series typically covers various frequencies within the same physical footprint. The '-OE' suffix indicates specific operational characteristics or packaging variations defined by the manufacturer. This family targets applications requiring small form factor timing solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 16.25 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal specifications. Cross-reference with other manufacturers offering equivalent quartz-based oscillators in the same footprint.
