QTM750-24.000MBE-T

Overview

The QTM750-24.000MBE-T is a standard CMOS quartz oscillator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 24 MHz with a supply voltage of 3.3V DC. The device features a frequency stability of ±50 ppm and functions within an operating temperature range of -40°C to +85°C. The physical package dimensions are 7.0mm x 5.0mm x 1.3mm in a 4-SMD, no-lead configuration. Maximum supply current is specified at 10mA. The output signal type is CMOS, suitable for digital clocking requirements.

Feature Summary

• Integrated CMOS output driver for direct logic interface compatibility
• Surface-mount 4-SMD no-lead package design for automated assembly
• Enable/Disable control functionality for power management

Applications

• Digital clock signal generation for microprocessors
• Timing reference for communication interfaces
• Synchronization circuits in embedded systems

Procurement Notes

Verify the manufacturer designation carefully, as this component appears under both QST and TXC Corporation branding in distributor listings. Confirm the specific datasheet version matches the required frequency tolerance and operating temperature range. Ensure the ordering suffix corresponds to the exact reel packaging quantity if bulk procurement is intended. Cross-reference the part number against official manufacturer catalogs to avoid substitution errors.

Selection Notes

Select this component when a 24 MHz CMOS clock source is required in a compact 7x5mm footprint. The ±50 ppm stability suits general-purpose digital timing rather than high-precision metrology. Verify that the 3.3V supply voltage aligns with the target system's power rails. Consider the enable/disable feature if dynamic power saving is necessary for the application design.

Part Context

This model belongs to the QTM750 series of standard crystal oscillators. The series offers various frequencies while maintaining consistent electrical characteristics and mechanical dimensions. It serves as a drop-in replacement for other 24 MHz oscillators sharing identical pinout and voltage specifications. The series is widely used in consumer electronics and industrial control modules requiring reliable timing signals.

Replacement Considerations

Direct substitutes include other 24 MHz CMOS oscillators in 4-SMD packages with matching 3.3V operation. Verify pin compatibility and output waveform integrity before substitution. Alternative manufacturers may offer similar performance but require verification of thermal and electrical limits.
