QTM216-25.000MBE-T

Overview

The QTM216-25.000MBE-T is a standard CMOS oscillator manufactured by QST, operating at a nominal frequency of 25 MHz. It utilizes a quartz crystal resonator and features a low electromagnetic interference (EMI) output. The device supports a supply voltage of 3.3V with an enable/disable control function. It is housed in a compact 4-SMD, no-lead package measuring 2.0x1.6 mm. The unit offers a frequency stability of ±50 ppm and operates within a temperature range of -40°C to +85°C, consuming a maximum supply current of 10 mA.

Feature Summary

• Low EMI CMOS output for signal integrity
• Integrated enable/disable control functionality
• Compact surface-mount form factor

Applications

• General clock distribution systems
• Embedded digital logic timing
• Communication interface synchronization

Procurement Notes

Verify the specific manufacturer designation on the component marking, as this model number appears across different manufacturers including TXC Corporation and QST. Confirm the exact frequency tolerance and temperature range specifications against the official datasheet provided by the specific supplier. Ensure the package dimensions match the required PCB footprint before integration.

Selection Notes

Select this component when a precise 25 MHz clock source is required for CMOS-compatible digital circuits. Consider the ±50 ppm stability requirement for timing-sensitive applications. Evaluate the 3.3V supply constraint and the need for active enable/disable control. The small 2.0x1.6 mm package is suitable for high-density board layouts where space is limited.

Part Context

This oscillator belongs to the QTM216 series, characterized by its 2.0x1.6 mm SMD package. The series includes various frequencies and is produced by multiple manufacturers, leading to potential nomenclature overlaps. It serves as a fundamental timing element in modern electronics, replacing discrete crystal and amplifier configurations with a single integrated solution.
