• Utilizes 1.8V single supply operation
• Housed in leadless SMD package for automated assembly

Oscillators Applications

• Embedded system clock generation
• Digital signal processing timing references
• Communication interface synchronization
• Microcontroller peripheral clocks

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and LVCMOS signaling is required. The enable/disable functionality makes it suitable for battery-powered devices needing power conservation. Consider the operating temperature range and frequency stability requirements to ensure compatibility with the application environment and performance standards.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same package form factor. The suffix OE indicates a specific configuration or packaging variant within the manufacturer's lineup. It shares physical dimensions with other models in the series but differs in electrical parameters such as frequency and potentially load capacitance.

Oscillators Replacement Considerations

Direct replacements must match the 14.753 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that substitute components support the enable/disable function if power control is critical. Cross-reference pinouts and thermal characteristics to ensure seamless integration without circuit modification.
