M143TCN 48.000000

Overview

The M143TCN 48.000000 is a standard crystal oscillator (XO) manufactured by MtronPTI, operating at a nominal frequency of 48 MHz. It utilizes an HCMOS/TTL output logic type and features a 5V enable/disable function for power management control. The component is housed in a compact 4-SMD, No Lead package with dimensions corresponding to the SMD7050-4P form factor. Designed for surface-mount applications, it serves as a precise clock source for digital circuits requiring stable timing signals.

Feature Summary

• Provides stable 48 MHz clock signal generation using internal crystal resonator
• Supports active low or high enable/disable control via dedicated pin
• Delivers compatible HCMOS and TTL output voltage levels
• Utilizes lead-free surface mount packaging for automated assembly

Applications

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

Procurement Notes

Verify the specific datasheet revision and electrical characteristics directly from MtronPTI official documentation before integration. Confirm that the 4-SMD footprint matches your PCB layout requirements. Ensure supply chain partners provide genuine components with traceable origin to avoid counterfeit risks. Cross-check enable/disable logic polarity against your circuit design specifications.

Selection Notes

Select this component when a fixed 48 MHz frequency is required with integrated enable functionality. Consider the SMD7050-4P package size constraints during mechanical design. Evaluate power consumption differences between enabled and disabled states. Verify compatibility with downstream logic families accepting HCMOS/TTL inputs without additional level shifting.

Part Context

This oscillator belongs to MtronPTI's standard XO series designed for general-purpose timing applications. The product line emphasizes reliability and compact form factors suitable for modern electronics manufacturing. It complements other frequency control solutions within the manufacturer's portfolio offering various frequencies and packages.

Replacement Considerations

Direct substitutes must match the 48 MHz frequency, HCMOS/TTL output, and 4-SMD package. Verify equivalent enable/disable functionality and electrical parameters. Consult manufacturer cross-reference lists for confirmed alternative part numbers with identical specifications.
