• Enable/Disable control capability for power management
• Compact 4-SMD No Lead surface-mount package

Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Procurement Notes

Verify the specific part number suffix against official Mercury Electronics documentation to confirm voltage and logic levels. Ensure the ordering code matches the required 1.8V specification and LVCMOS output type. Cross-reference with authorized distributors to confirm availability and authenticity before purchase.

Selection Notes

Select this component when a 57.425 MHz clock source with LVCMOS outputs is required. The 1.8V supply voltage suits low-power digital circuits. The enable/disable feature allows for system-level power optimization. Verify that the 4-SMD package dimensions fit the target PCB layout constraints.

Part Context

This model belongs to the QHTF series of standard oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The '18' prefix indicates the 1.8V operating voltage range. The 'OE' suffix denotes the Enable/Disable function variant within the product line.

Replacement Considerations

Compatible substitutes include other 57.425 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications before substitution. Check datasheets for equivalent enable/disable functionality.
