18QHTF21-65.360-OE

Overview

The 18QHTF21-65.360-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 65.36 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features integrated enable and disable control functionality
• Utilizes a low-profile 4-SMD no lead surface mount package

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

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 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a 65.36 MHz clock source is required with LVCMOS outputs. Consider the 1.8V operating voltage constraint and the need for software-controllable enable/disable features. Evaluate the 4-SMD package size against available board space constraints compared to larger through-hole or alternative SMD oscillator packages.

Part Context

This model belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The manufacturer specializes in quartz crystal products and has established history in Taiwan's frequency control industry. This specific part represents a surface-mount solution within their broader portfolio of timing components.

Replacement Considerations

Direct substitutes must match the 65.36 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics before substituting with other manufacturers' offerings to ensure functional equivalence.
