QTM750-75.000MBE-T

Overview

The QTM750-75.000MBE-T is a standard CMOS quartz oscillator manufactured by TXC Corporation, part of the QTM750 series. It operates at a nominal frequency of 75 MHz with a frequency stability of ±50 ppm across an industrial temperature range of -40°C to +85°C. The device utilizes a 3.3V supply voltage and features an enable/disable control function. It is housed in a compact 7.0mm x 5.0mm SMD package with four terminals.

Feature Summary

• CMOS output signal compatible with digital logic circuits
• Integrated enable and disable functionality for power management
• Industrial temperature range operation from -40°C to +85°C
• Compact surface-mount design suitable for space-constrained applications

Applications

• General-purpose clock generation for embedded systems
• Timing reference for microcontrollers and processors
• Communication interface synchronization
• Consumer electronics timing circuits

Procurement Notes

Verify the manufacturer designation carefully, as this component is associated with both TXC Corporation and QST Products LLC in public records. Confirm the specific suffix 'BE' indicates the correct voltage and package variant. Ensure the requested quantity aligns with factory packaging requirements, typically specified in multiples of 1000 units. Cross-reference the datasheet version to confirm compatibility with your system's electrical specifications before finalizing procurement.

Selection Notes

Select this oscillator when a 75 MHz CMOS clock source is required within a 7x5mm footprint. The ±50 ppm stability suits general digital applications rather than high-precision RF systems. Verify that the 3.3V operating voltage matches the target board's power rail. Consider the enable pin requirement if dynamic power saving is necessary for the application design.

Part Context

This component belongs to the QTM750 series of standard oscillators. The series offers various frequencies including 4.096 MHz, 32.768 MHz, 50 MHz, 125 MHz, and 133 MHz. All variants share similar physical dimensions and electrical characteristics, differing primarily in output frequency and specific suffix codes indicating package or tolerance variations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacements may include other 75 MHz CMOS oscillators in a 7x5mm SMD package with 3.3V operation and ±50 ppm stability, but functional equivalence must be verified against the original datasheet.
