Oscillators Procurement Notes

Verify the specific suffix (OE) against the manufacturer's official documentation to confirm the exact enable/disable functionality and voltage tolerance. Ensure the ordering part number matches the required frequency and package type precisely. Cross-reference the datasheet for absolute maximum ratings before integration to prevent component damage during assembly or operation.

Oscillators Selection Notes

Select this component when a precise 2.5625 MHz timing source is required with minimal footprint. The 1.8V operating voltage makes it suitable for low-voltage digital logic families. Consider the enable/disable feature if system power efficiency is a priority. Confirm that the LVCMOS output swing meets the input requirements of the receiving circuitry.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series offers various frequencies within a standardized small outline no-lead package. Mercury Electronics has been a pioneer in the crystal industry since 1973, providing reliable timing solutions for global electronics manufacturing.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical package and electrical characteristics but different frequencies, such as 18QHTF21-6.300-OE or 18QHTF21-30.000-OE, provided the system timing requirements allow for frequency adjustment. Verify pinout compatibility before substitution.
