M244FCN 25.000000

Overview

The M244FCN 25.000000 is a crystal oscillator manufactured by MtronPTI, designed for surface-mount applications. It operates at a fixed frequency of 25.000000 MHz and utilizes HCMOS output logic levels. The device is powered by a single 3.3V supply voltage and features a compact 4-SMD, no-lead package with dimensions of 7.00mm x 5.00mm. This component provides a stable clock signal suitable for digital systems requiring precise timing synchronization.

Feature Summary

• Generates a stable 25 MHz clock signal using internal crystal technology
• Outputs HCMOS compatible logic levels for direct interface with digital circuits
• Operates on a standard 3.3V power supply rail
• Utilizes a leadless SMD package for automated surface-mount assembly

Applications

• Digital system clock generation
• Microprocessor timing sources
• Communication interface synchronization
• Embedded controller clock inputs

Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency tolerance and load capacitance requirements are met for your design. Confirm that the 3.3V operating voltage aligns with your system's power architecture. Check the datasheet for recommended soldering profiles to maintain package integrity during assembly. Ensure the 7x5mm footprint matches your PCB layout constraints.

Selection Notes

Select this component when a precise 25 MHz reference is required for HCMOS-compatible logic interfaces. Consider the 3.3V supply constraint and the physical size limitations of the 4-SMD package. Evaluate the need for surface-mount compatibility versus through-hole alternatives if space is not a primary constraint. Verify that the output drive strength meets the input requirements of the downstream circuitry.

Part Context

This part belongs to MtronPTI's line of tiny wafer-level surface-mount oscillators. These devices are engineered for high reliability in compact electronic assemblies. The M244 series typically offers low phase noise and stable performance across temperature ranges, making them suitable for demanding digital applications where space and power efficiency are critical factors.

Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 3.3V supply, HCMOS output, and 7x5mm package dimensions. Verify pinout compatibility and electrical characteristics before substitution. Cross-reference with other manufacturers offering similar surface-mount crystal oscillators to ensure functional equivalence in the target application.
