QTM750-32.768MBE-T

Overview

The QTM750-32.768MBE-T is a standard clock oscillator manufactured by QST Products, LLC. It operates at a frequency of 32.768 MHz with CMOS output signal levels. The device supports an operating voltage of 3.3V DC and features enable/disable functionality. It utilizes a ceramic package with dimensions of 7x5x1.3mm in a surface-mount configuration. The unit provides frequency stability of ±50ppm and functions within a temperature range of -40°C to +85°C.

Feature Summary

• CMOS output signal compatibility for digital logic integration
• Integrated enable and disable control capability
• Ceramic body construction for environmental robustness

Applications

• Real-time clock circuits requiring precise timing references
• Microcontroller system clock generation
• Embedded communication interface synchronization

Procurement Notes

Verify the manufacturer designation carefully, as TXC Corporation also lists this part number in their catalog. Confirm that the specific order matches the QST Products, LLC specification sheet rather than the TXC datasheet. Ensure the enable/disable pin configuration aligns with the target circuit design requirements before finalizing procurement.

Selection Notes

Select this component when a 32.768 MHz reference is required for low-power or real-time applications. The CMOS output level simplifies interfacing with standard digital logic families without additional buffering. The wide operating temperature range supports deployment in industrial environments where thermal stability is critical for maintaining frequency accuracy.

Part Context

This model belongs to the QTM750 series of quartz oscillators from QST. The series includes various frequencies such as 4.096 MHz, 30 MHz, and 50 MHz variants. All members share the same 7x5mm footprint and 3.3V supply characteristics, allowing for consistent board layout strategies across different timing requirements within a single product family.

Replacement Considerations

QTM750-32.768MBE-T is functionally interchangeable with other 32.768 MHz CMOS oscillators in the 7x5mm SMD package. Verify pinout compatibility and enable signal polarity when substituting with equivalent parts from other manufacturers.
