QTM325-25.000MBB-T

Overview

The QTM325-25.000MBB-T is a surface-mount crystal oscillator manufactured by QST, operating at a nominal frequency of 25.0000 MHz. It utilizes CMOS output technology and is housed in a compact 3.2mm x 2.5mm SMD package. The device operates on a 3.3V supply voltage and provides a frequency stability of +/-50ppm over an industrial temperature range of -10°C to +70°C. This component is designed for standard clock applications requiring reliable timing signals in space-constrained electronic designs.

Feature Summary

• CMOS output interface for digital logic compatibility
• Compact 3.2mm x 2.5mm surface mount footprint
• Industrial temperature range operation from -10°C to +70°C

Applications

• Standard clock signal generation
• Embedded system timing references
• Digital communication interfaces

Procurement Notes

Verify the manufacturer designation carefully, as this part number appears associated with both TXC Corporation and QST in distributor listings. Confirm the specific datasheet version and electrical specifications match your design requirements before procurement. Ensure the package dimensions and pinout align with your PCB layout constraints. Cross-reference the official manufacturer documentation to resolve any discrepancies between supplier data sheets.

Selection Notes

Select this component when a 25MHz CMOS clock source is required within a 3.2x2.5mm envelope. The +/-50ppm stability suits general-purpose digital circuits rather than high-precision RF applications. Consider the -10°C to +70°C operating range against your environmental conditions. Verify power consumption and load capacitance requirements if driving multiple inputs or long traces.

Part Context

This oscillator belongs to the QTM325 series, which features standardized 3.2mm x 2.5mm packages. The suffix 'BB' typically denotes specific packaging or tolerance variations within the product line. Similar parts in the series offer different frequencies such as 48MHz, maintaining consistent form factors for board design flexibility across various product generations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Direct replacements should be verified through official manufacturer cross-reference tools or authorized distributor databases to ensure electrical and mechanical compatibility.
