Procurement Notes

Verify the manufacturer designation carefully, as sources list both QST and TXC Corporation for this part number series. Confirm the specific suffix 'MBD-T' matches the required frequency and voltage specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet to confirm package dimensions and electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a 47.9952 MHz timing source is required within a 3.3V system. The standard CMOS output is suitable for direct interfacing with logic gates without additional buffering. Consider the 2.50mm x 2.00mm footprint for space-constrained PCB layouts. Verify that the operating temperature range and stability requirements align with the application environment.

Part Context

This oscillator belongs to the QTM252 series, which includes various frequencies and voltage options such as the QTM252-106.250MBE-T and QTM252E-40.000MCJ-T. The series offers different supply voltages and temperature ranges across variants. The 'E' suffix often denotes low EMI versions, while the base model provides standard performance.

Replacement Considerations

Direct substitutes include other QTM252 series parts with matching frequencies if available. Generic replacements must match the 47.9952 MHz frequency, 3.3V supply, and CMOS output type. Ensure any alternative component fits the 2.50mm x 2.00mm SMD package and maintains RoHS compliance.
