• Includes Enable/Disable functionality for power control
• Operates at 1.8V supply voltage

Applications

• General clock signal generation
• Digital system timing references
• Embedded controller clock inputs

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V operating voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a precise 65.963 MHz clock source is required for low-voltage digital circuits. The LVCMOS interface ensures direct compatibility with standard logic families without additional level shifting. The enable/disable feature allows for dynamic power savings in battery-operated or energy-efficient designs requiring clock gating capabilities.

Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequency options within a standardized small outline package. The 'OE' suffix typically denotes specific operational characteristics or packaging variants defined by the manufacturer for this product line.

Replacement Considerations

Direct substitutes include other 65.963 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution. Cross-reference with Mercury Electronics part numbers like 18QHTF21-67.563-OE only if frequency adjustment is acceptable.
