Procurement Notes

Verify the specific manufacturer designation, as this part number appears in catalogs associated with both QST Products, LLC and TXC Corporation. Confirm the exact supply voltage and stability grade required for your design against the official datasheet before ordering. Ensure the package dimensions match your PCB layout constraints.

Selection Notes

Select this component when a 26 MHz reference is needed in a minimal footprint. It is appropriate for designs prioritizing size reduction over ultra-high precision. Consider the ±50ppm stability limit for applications sensitive to long-term drift. Verify compatibility with the target logic family voltage levels.

Part Context

This oscillator belongs to the QTM252 series, which provides various frequency options within the same 2520 package. The series covers frequencies from 4 MHz to 125 MHz, offering a standardized solution for multiple interface requirements including USB, SATA, and PCIe without changing the mechanical form factor.

Replacement Considerations

Direct substitutes include other 26 MHz oscillators in the 2520 package such as the QTM252-26.000MCM-T or equivalent parts from TXC Corporation. Ensure replacement parts match the 3.3V supply requirement and CMOS output characteristics.
