18QHTF21-60.800-OE

Overview

The 18QHTF21-60.800-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 60.8 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. A key functional characteristic is the inclusion of an enable/disable control pin, allowing for power management flexibility in circuit designs. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Feature Summary

• LVCMOS output logic interface
• Integrated enable/disable functionality
• Compact 4-SMD no lead package

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 60.8 MHz reference is required with low power consumption constraints. The enable/disable feature makes it suitable for battery-operated devices or systems requiring dynamic power state management. Consider the operating temperature range and stability requirements relative to the application environment to ensure long-term reliability.

Part Context

This part belongs to the Mercury Electronics XO series, which focuses on quartz-based timing solutions. Mercury Electronic Ind. Co. Ltd has established itself as a pioneer in Taiwan's quartz industry, manufacturing various frequency control products including crystals, oscillators, and filters since 1973. This specific model represents their standard output oscillator line.

Replacement Considerations

Direct substitutes include other 60.8 MHz LVCMOS oscillators from different manufacturers if pin compatibility allows. Verify that alternative parts support the same 1.8V supply voltage and offer comparable enable/disable functionality. Check package dimensions to ensure mechanical interchangeability without redesigning the PCB layout.
