QTM750-3.6864MBB-T

Overview

The QTM750-3.6864MBB-T is a standard CMOS quartz crystal oscillator manufactured by TXC Corporation under the QST brand. It operates at a frequency of 3.6864 MHz with a frequency stability of ±50 ppm. The device utilizes a 3.3V supply voltage and features a 4-SMD, no-lead surface mount package with dimensions of 7.0mm x 5.0mm. It is designed for operation within an industrial temperature range of -40°C to +85°C.

Feature Summary

• CMOS output interface for digital logic compatibility
• Surface mount construction in a compact 7.0x5.0mm footprint
• Industrial temperature rating for broad environmental resilience

Applications

• General clock signal generation for embedded systems
• Timing reference for microprocessors and microcontrollers
• Data communication interface synchronization

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by TXC Corporation. Confirm that the specific suffix 'BB' aligns with your required frequency tolerance and temperature range specifications before ordering. Ensure compatibility with the 3.3V logic levels of your target circuit design.

Selection Notes

Select this part when a standard fixed-frequency CMOS oscillator is required rather than a voltage-controlled variant. Compare against other suffixes in the QTM750 series to ensure the specific stability and temperature grade matches the application requirements. Verify that the 4-pin SMD package fits the available PCB real estate constraints.

Part Context

This component belongs to the QTM750 series of surface-mount crystal oscillators. The series offers various frequencies and stability options within a standardized 7.0x5.0mm package. It serves as a direct replacement for legacy through-hole crystals where precise timing and ease of assembly are prioritized.

Replacement Considerations

Direct substitutes include other QTM750 series variants with identical pinout and dimensions but different frequency or stability ratings, such as QTM750-3.6864MBE-T or QTM750-3.6864MBA-T, provided the electrical parameters meet system needs.
