• Includes hardware enable and disable functionality
• Designed for surface mount assembly via 4-SMD no lead package

Applications

• General clock signal generation
• Digital system timing references
• Embedded electronics requiring low voltage operation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational specifications to ensure reliable performance. Ensure the PCB footprint matches the 4-SMD no lead package dimensions provided in the official datasheet.

Selection Notes

Select this component when a precise 13.275 MHz reference is required with low power consumption. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable pin utility for power management strategies in battery-operated or energy-efficient designs.

Part Context

This model belongs to the Mercury Electronics standard XO series, which provides reliable frequency control solutions. The manufacturer has extensive experience in quartz crystal production since 1973. This specific part represents a common configuration within their SMD oscillator portfolio.

Replacement Considerations

Direct substitutes must match the 13.275 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility and electrical parameters such as phase noise and jitter if available in official documentation.
