18QHTF21-60.138-OE

Overview

The 18QHTF21-60.138-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 60.138 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, no lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control functionality
• Compact 4-SMD no lead surface mount package

Applications

• General purpose clock signal generation
• Digital system timing reference
• Embedded controller clock input

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system 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 low-voltage 1.8V operation is required alongside standard LVCMOS signaling levels. The integrated enable pin allows for dynamic power control, making it suitable for battery-operated or energy-efficient designs. Consider the operating temperature range and frequency stability specifications to ensure reliability under the intended environmental conditions of the final application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in producing oscillators and crystals. This specific model represents a standard XO variant within their portfolio, distinguished by its specific frequency and package type.

Replacement Considerations

Direct replacements must match the 60.138 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify that any substitute component offers compatible electrical characteristics and physical dimensions to ensure seamless integration without redesigning the host circuit board.
