QTM252E-30.000MDM-T

Overview

The QTM252E-30.000MDM-T is a standard CMOS quartz oscillator manufactured by TXC Corporation under the QST brand. It operates at a nominal frequency of 30 MHz with a stability of ±50 ppm. The device utilizes a crystal base resonator and functions within a supply voltage range of 1.8V to 2.5V. It features an enable/disable control interface and is housed in a compact 4-pin surface-mount package measuring 2.5mm x 2.0mm x 0.8mm. The component supports extended industrial temperature ranges from -40°C to +125°C.

Feature Summary

Low electromagnetic interference (EMI) design for signal integrity
Integrated enable and disable control functionality
Compact surface-mount footprint for space-constrained layouts

Applications

Embedded communication systems requiring precise timing
Industrial control equipment operating in extreme temperatures
Consumer electronics utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific suffix code against official datasheets to confirm voltage, load capacitance, and temperature grade. Ensure the ordering part number matches the required operational parameters exactly. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference manufacturer documentation for compliance certifications before integration.

Selection Notes

Select this component when a 30 MHz clock source is required with strict size limitations. Consider the ±50 ppm stability requirement for system synchronization accuracy. Evaluate the 1.8V supply compatibility with the target logic family. Verify that the enable pin functionality aligns with power management strategies.

Part Context

This oscillator belongs to the QTM252E series, which provides low-profile timing solutions. The series is designed for applications demanding high reliability and minimal electromagnetic noise. It serves as a direct replacement for legacy through-hole oscillators in modern surface-mount designs.

Replacement Considerations

Compatible substitutes include other 30 MHz CMOS oscillators in 2.5x2.0 packages with matching voltage and stability ratings. Verify pinout compatibility and electrical specifications before substitution. Consult manufacturer cross-reference lists for verified alternative part numbers.
