Procurement Notes

Verify the specific suffix 'BB' against official QST documentation to confirm pinout and electrical characteristics. Ensure the required frequency tolerance of 50 ppm aligns with system timing requirements. Confirm the 3.3V supply voltage compatibility with the target circuit design before procurement.

Selection Notes

Select this component when a 40 MHz CMOS clock source is required in a small form factor. Consider the 50 ppm stability for applications needing moderate precision. Verify that the 3.3V operating voltage matches the system power rails. Evaluate the -40°C to +85°C range against environmental conditions.

Part Context

This part belongs to the QTM series of surface-mount oscillators from QST. These devices are designed for high-reliability applications requiring stable clock signals. The series offers various frequencies and packages to suit different size constraints. The CMOS output ensures compatibility with standard digital logic families.

Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 50 ppm stability, 3.3V supply, and 5x3.2mm package. Verify pin compatibility and output waveform specifications. Cross-reference with other manufacturers' 40 MHz CMOS oscillators in similar SMD packages.
