QTM252J-10.000MDJ-T

Overview

The QTM252J-10.000MDJ-T is a standard clock oscillator manufactured by TXC Corporation under the QST brand designation, housed in a 4-SMD surface-mount package measuring 2.5x2.0 mm. It operates with a CMOS output interface and requires a supply voltage of 1.8V. The device provides a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to 105°C. Maximum supply current is specified at 22mA. This component is classified as a low jitter and phase noise quartz oscillator suitable for precision timing applications.

Feature Summary

• Features a compact 2.5x2.0 mm surface-mount ceramic package design.
• Provides CMOS output signals with low jitter and phase noise characteristics.
• Includes enable/disable functionality for power management control.

Applications

• Precision timing circuits requiring stable clock references
• Embedded systems operating in extended industrial temperature ranges
• Digital signal processing interfaces

Procurement Notes

Verify the manufacturer origin carefully, as listings may attribute this part to either TXC Corporation or QST. Confirm the specific suffix MDJ-T matches the required 1.8V supply voltage and ±50ppm stability specifications. Ensure the operating temperature range meets the -40°C to 105°C requirement for your application environment before finalizing procurement orders.

Selection Notes

Select this component when a small form factor 2.5x2.0 mm oscillator is required alongside strict 1.8V logic compatibility. The ±50ppm stability rating suits general digital synchronization needs rather than high-precision metrology. Consider the 22mA maximum current draw for power budget calculations in battery-operated or energy-constrained designs.

Part Context

This model belongs to the QTM252 series of quartz oscillators, which are characterized by their small footprint and robust performance across wide temperature ranges. The J suffix typically denotes specific electrical parameters such as the 1.8V supply and CMOS output type, distinguishing it from other variants in the family that may support different voltages or packages.

Replacement Considerations

Direct substitutes include other 2.5x2.0 mm 1.8V CMOS oscillators with ±50ppm stability, such as the QTM252J-48.000MDJ-T for different frequencies. Verify pinout compatibility and thermal characteristics when swapping between manufacturers like TXC or generic equivalents.
