QTM750-25.000MDE-T

Overview

The QTM750-25.000MDE-T is a standard clock oscillator manufactured by QST, operating at a frequency of 25 MHz. It utilizes CMOS output logic and functions with a supply voltage of 3.3V. The device features an enable/disable control pin for power management. It is housed in a 4-SMD, No Lead package with dimensions of 7.0mm x 5.0mm x 1.3mm. The unit supports an operating temperature range of -40°C to +85°C and maintains a frequency stability of ±50ppm.

Feature Summary

• Integrates an enable/disable function for active power management
• Utilizes CMOS output interface for digital logic compatibility
• Provides high frequency stability within industrial temperature ranges

Applications

• Embedded system clock generation
• Microcontroller timing references
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix 'MBE' against datasheets to confirm the presence of the enable/disable pin, as variations exist within the QTM750 series. Ensure the 3.3V supply requirement aligns with the target circuit design. Confirm RoHS compliance status through official manufacturer documentation prior to integration into environmentally regulated assemblies.

Selection Notes

Select this component when a 25 MHz reference with low-power standby capabilities is required. The 4-SMD package suits space-constrained PCB layouts. Compare against similar models like the MDE variant if enable functionality is not needed, ensuring the voltage level matches the 3.3V specification rather than lower voltage alternatives.

Part Context

This part belongs to the QTM750 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options. The specific model distinguishes itself through its 3.3V operation and integrated control pin, differentiating it from basic uncontrolled oscillators in the same footprint family.

Replacement Considerations

Direct substitutes include other 25MHz 3.3V CMOS oscillators in 7x5mm packages. Verify pinout compatibility, specifically the enable pin configuration, before swapping with generic equivalents.
