M7S43FAJ 8.000000

Overview

The M7S43FAJ 8.000000 is a surface-mount crystal oscillator from the MtronPTI M7S series, housed in a 4-SOJ ceramic package with a 5.08mm pitch. It operates at a nominal frequency of 8 MHz and supports both HCMOS and TTL output logic levels. The device functions within a supply voltage range of 3.3V to 5.0V, ensuring compatibility with standard digital logic families. Designed for reliability, it features low jitter characteristics and is available in RoHS-compliant versions, making it suitable for various electronic applications requiring precise clock signals.

Feature Summary

• Supports dual HCMOS and TTL output logic levels for broad interface compatibility
• Utilizes a compact 9x14 mm J-lead ceramic package for surface mount integration
• Operates on standard 3.3V or 5.0V power supplies
• Features low jitter performance for stable clock signal generation

Applications

• Digital system clock generation
• Microprocessor timing references
• Communication equipment synchronization
• Test and measurement instrument clocks

Procurement Notes

Verify the specific suffix (e.g., -R) if RoHS compliance is required, as standard versions may differ. Confirm the exact frequency tolerance and load capacitance requirements against your circuit design specifications. Ensure the 4-SOJ footprint matches your PCB layout constraints. Check for any lead-free plating variations if environmental regulations apply to your assembly process.

Selection Notes

Select this component when a reliable 8 MHz clock source is needed for HCMOS/TTL logic interfaces. Consider the M7S series for its robust ceramic packaging and wide operating temperature range compared to plastic packages. Evaluate the 3.3V/5.0V versatility if your system uses mixed voltage domains. Compare against higher-frequency models if speed requirements exceed 8 MHz.

Part Context

This part belongs to the M7S series of clock oscillators manufactured by MtronPTI. The series is characterized by its use of J-lead ceramic packages, offering durability and thermal stability. These oscillators are designed to replace discrete crystal and IC combinations, providing a complete, pre-tuned clock solution in a small form factor suitable for modern electronics manufacturing.

Replacement Considerations

Direct replacements include other M7S series variants with different frequencies, such as M7S43TBJFREQ1 or M7S43FAJ-R125.0000MHZ, provided the frequency requirement changes. Cross-brand equivalents should match the 4-SOJ package, 8 MHz frequency, and HCMOS/TTL output type. Verify pinout compatibility before substitution.
