QTT252-24.000MCG-T

Overview

The QTT252-24.000MCG-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST, operating at a nominal frequency of 24 MHz. It utilizes a clipped sine wave output and functions within a supply voltage range of 2.5V. The device features an enable/disable control function and is housed in a compact surface-mount package designed for integration into timing-critical electronic circuits requiring stable clock signals.

Feature Summary

• Temperature compensation ensures frequency stability across varying thermal conditions
• Integrated enable and disable functionality for power management control
• Clipped sine wave output signal suitable for digital logic interfaces

Applications

• Precision timing reference in communication modules
• Clock source for microcontroller systems
• Synchronization components in data acquisition equipment

Procurement Notes

Verify the specific manufacturing lot and date code upon receipt to ensure compliance with project timelines. Confirm that the received component matches the exact part number designation, including all suffix characters, as variations may indicate different electrical characteristics or packaging configurations. Ensure storage conditions align with manufacturer recommendations to maintain component integrity prior to assembly.

Selection Notes

Select this component when a 24 MHz clock signal with enhanced thermal stability is required compared to standard crystals. The 2.5V supply requirement dictates compatibility with low-voltage logic families. Consider the clipped sine wave output format against system input thresholds. Evaluate the enable/disable pin utility for applications necessitating active power state management during idle periods.

Part Context

This oscillator belongs to the QTT252 series from QST, a line of surface-mount timing devices. The series typically includes variants with different frequencies and voltage levels, such as 3.3V options. The 252 package size indicates a small form factor suitable for space-constrained printed circuit board layouts in modern consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 24 MHz TCXOs in similar packages with compatible voltage and output types. Verify equivalent frequency tolerance and phase noise specifications before substitution. Cross-reference pinout definitions to ensure functional compatibility without hardware modification.
