QTM325-10.000MBD-T

Overview

The QTM325-10.000MBD-T is a standard CMOS quartz oscillator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 10 MHz with a stability of ±25 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 function for power management. Housed in a compact 4-SMD, No Lead package measuring 5.0mm x 3.2mm, it delivers a square wave output suitable for high-speed digital circuits.

Feature Summary

• Integrated enable/disable control functionality for active power management
• CMOS output signal generation compatible with standard logic families
• Industrial-grade temperature rating ensuring reliability in harsh environments

Applications

• High-speed data communication interfaces
• Network infrastructure equipment
• Consumer electronics requiring precise timing

Procurement Notes

Verify the specific manufacturer part number against official QST documentation to confirm pinout compatibility and electrical specifications. Ensure that the required operating voltage and load conditions match the target circuit design before procurement. Cross-reference the package dimensions with the PCB footprint library to guarantee accurate physical integration during assembly.

Selection Notes

Select this component when a low-profile, surface-mount oscillator with enable/disable capability is required. It is suitable for designs needing 10 MHz timing with ±25 ppm stability. Consider the 3.3V supply constraint and the 5.0x3.2mm package size relative to available board space. Verify that the CMOS output swing meets the input requirements of the downstream clocking devices.

Part Context

This model belongs to the QTM325 series of MHz CMOS oscillators from QST. The series covers frequencies from 1MHz to 133MHz in a 3.2mm x 2.5mm form factor. This specific variant provides a 10MHz output with enhanced stability compared to basic series models, targeting applications demanding reliable clock sources in compact electronic systems.

Replacement Considerations

Compatible substitutes include other 10MHz CMOS oscillators with ±25ppm stability and 3.3V operation. Ensure replacement parts maintain the same 4-SMD no-lead package dimensions and pin configuration. Verify that alternative components support the required enable/disable feature if power management is critical to the system design.
