Procurement Notes

Verify the specific manufacturer designation as sources attribute this part to both TXC Corporation and QST. Confirm the exact package outline and pin configuration against the official datasheet before integration. Ensure the supply voltage matches the 3.3V requirement. Validate the frequency tolerance and temperature range against application constraints. Cross-reference the ordering suffix to ensure correct packaging and specifications.

Selection Notes

Select this component when a stable 27 MHz reference is required for CMOS logic circuits. Consider the ±50ppm stability for applications demanding moderate precision. Evaluate the 10mA current consumption against power budget requirements. Verify compatibility with the 3.3V logic level. Assess the need for the enable/disable feature for power saving strategies. Compare physical footprint constraints against the 7.0x5.0mm package size.

Part Context

This oscillator belongs to the QTM750 series, designed for surface mount applications. The series offers various frequencies within the same form factor. It serves as a replacement for through-hole oscillators in space-constrained designs. The CMOS output simplifies interfacing with modern digital processors. The enable pin allows for dynamic power control during idle states.

Replacement Considerations

Direct substitutes include other 27 MHz CMOS oscillators in 7.0x5.0mm packages with similar electrical characteristics. Verify pinout compatibility if replacing with different manufacturers. Check for equivalent frequency stability and supply voltage ranges. Ensure the replacement supports the required enable/disable functionality.
