18QHTF21-76.000-OE

Overview

The 18QHTF21-76.000-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 76 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Enable/Disable control functionality 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 suffix OE against official Mercury Electronics documentation to confirm the enable/disable feature and voltage level. Ensure the 4-SMD no-lead footprint matches the target PCB design. Cross-reference the 76 MHz frequency requirement with system clock specifications before ordering.

Selection Notes

Select this component when a 1.8V supply and LVCMOS outputs are required. The enable/disable pin allows for active low power states. Consider the 4-SMD package size for space-constrained designs. Verify temperature range and load capacitance requirements against the application environment.

Part Context

This part belongs to the Mercury Electronics XO series, which includes various frequencies and packages. The 18QHTF21 series typically offers standard performance levels. Other variants in this family may differ in frequency, voltage, or package type while maintaining similar form factors.

Replacement Considerations

Direct substitutes must match the 76 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Check manufacturer datasheets for equivalent parts from other vendors offering compatible timing solutions with identical pinouts and electrical characteristics.
