QTM325-26.000MBE-T

Overview

The QTM325-26.000MBE-T is a standard clock oscillator manufactured by QST, operating at a nominal frequency of 26 MHz. It utilizes CMOS output technology and is housed in a surface-mount ceramic package with dimensions of 3.2 x 2.5 x 1.0 mm. The device supports a supply voltage of 3.3 VDC and maintains a frequency stability of ±50 ppm across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides stable timing signals via CMOS output interface
• Encased in a compact ceramic SMD package for reliable performance
• Operates within a wide industrial temperature range

Applications

• General-purpose digital circuit timing
• Microcontroller clock sources
• Communication equipment synchronization

Procurement Notes

Verify the specific suffix 'BE' against official QST documentation to confirm the exact frequency tolerance and temperature range specifications. Ensure compatibility with 3.3V logic levels and check footprint requirements for the 3.2x2.5mm package before integration into the design.

Selection Notes

Select this component when a 26 MHz reference is required for space-constrained designs. The ±50 ppm stability suits general applications where high precision is not critical. Confirm that the CMOS output swing matches the receiving input thresholds of the target system.

Part Context

This part belongs to the QTM325 series of quartz crystal oscillators from QST. These components are designed as drop-in replacements for discrete crystal resonators, offering integrated oscillator functionality in a standardized small outline package suitable for automated assembly processes.

Replacement Considerations

Compatible substitutes include other 26 MHz oscillators in the same 3.2x2.5mm package with matching 3.3V operation and ±50 ppm stability, such as variants from manufacturers like TXC or Abracon, provided pinout and electrical characteristics align.
