Oscillators Procurement Notes

Verify that the specific part number matches the required 25 MHz frequency and 3.3 V operating voltage. Confirm the package type is the 4-SMD no-lead variant. Ensure the manufacturer is ILSI to guarantee compatibility with design specifications. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Oscillators Selection Notes

Select this component when a 25 MHz CMOS clock source is required with low profile dimensions. The 3.3 V supply requirement must align with the system power rails. Consider the enable/disable feature if power management or clock gating is necessary for the application. Verify thermal performance within the specified operating temperature range.

Oscillators Part Context

This model belongs to the ISM97 series of surface-mount oscillators from ILSI. The series includes various frequencies and voltage options, such as the ISM97-3351AH-50.0000 for 50 MHz operation. The ISM97-3351AH-25.000MHZ specifically targets applications needing a 25 MHz reference with CMOS outputs in a compact form factor.

Oscillators Replacement Considerations

Direct substitutes include other 25 MHz CMOS oscillators in 3225 packages from different manufacturers, provided electrical parameters match. Cross-reference with ISM97-3251BH-25.000MHZ for similar specifications. Ensure pinout and voltage levels are identical before substitution.
