• Enable/Disable functionality for active power management
• Quartz-based timing stability with SMD no-lead packaging

Applications

• General-purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Procurement Notes

Verify the exact datasheet specifications directly from Mercury Electronics Ind. Co. Ltd before integration. Confirm that the 1.8V supply and LVCMOS levels match your target circuit design. Ensure the 4-SMD package footprint aligns with your PCB layout requirements to avoid assembly issues.

Selection Notes

Select this component when a 114.215 MHz clock source with low-voltage operation is required. The Enable/Disable feature allows for dynamic power control, making it suitable for battery-operated or energy-efficient designs. Verify thermal and electrical constraints against the official datasheet parameters.

Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The suffix OE indicates specific enable/disable characteristics within this product line.

Replacement Considerations

Cross-reference with other 18QHTF21 variants such as 18QHTF21-117.675-OE if frequency adjustments are permissible. Ensure substitute parts maintain the same 4-SMD package and LVCMOS logic levels for direct compatibility.
