• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing systems
• Communication equipment clocking
• Consumer electronics timing references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper solder joint integrity and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a precise 29.972 MHz reference is required for LVCMOS-compatible digital circuits. The choice is driven by the need for low-power operation at 1.8V and the availability of hardware enable/disable controls. Consider the small form factor of the 4-SMD package for space-constrained designs where surface-mount technology is preferred over through-hole alternatives.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics XO series, which provides standard frequency generation solutions. The brand has established expertise in quartz crystal manufacturing since 1973. This specific model represents a standardized product offering within their portfolio, focusing on reliable performance for general-purpose timing applications in electronic devices.

Oscillators Replacement Considerations

Direct replacements must match the 29.972 MHz frequency, LVCMOS output type, and 1.8V supply voltage. Verify pinout compatibility for the 4-SMD no-lead package. Cross-reference with other Mercury Electronics models in the same series or equivalent offerings from other manufacturers that support identical electrical parameters and physical dimensions.
