QTM252J-48.000MBJ-T

Overview

The QTM252J-48.000MBJ-T is a standard clock oscillator manufactured by TXC Corporation, distributed by QST Products. It features a 2.5x2.0 mm surface-mount package with CMOS output. The device operates at a supply voltage of 3.3V and provides a frequency stability of ±50ppm across an operating temperature range of -40°C to +105°C.

Feature Summary

• Low jitter and phase noise performance
• CMOS output signal compatibility
• Compact 2.5x2.0 mm ceramic package

Applications

• Precision timing applications in electronic circuits
• General purpose clock generation for digital systems

Procurement Notes

Verify the manufacturer designation on official documentation, as sources list both TXC Corporation and QST Products. Confirm the specific ordering suffix matches the required voltage and stability specifications. Ensure the component meets the intended thermal and electrical requirements for the target application before procurement.

Selection Notes

Select this model when a compact 2.5x2.0 mm footprint is required alongside 3.3V operation. The ±50ppm stability suits general timing needs rather than high-precision references. Consider alternative suffixes if different supply voltages or extended temperature ranges are necessary for the design.

Part Context

This component belongs to the QTM252J series of low jitter quartz oscillators. The series offers various frequencies and voltage options within the same small form factor. It serves as a direct replacement for other SMD2520-4P oscillators requiring similar electrical characteristics and physical dimensions.

Replacement Considerations

Check datasheets for compatible parts from other manufacturers offering identical 2.5x2.0 mm packages and 3.3V CMOS outputs. Verify that substitute components meet the same ±50ppm stability and -40°C to +105°C temperature range specifications.
