18QHTF21-12.463-OE

Overview

The 18QHTF21-12.463-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 12.463 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

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

Applications

• General clock signal generation
• Digital system timing references
• Embedded controller circuits

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.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The integrated enable pin allows for power management strategies in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs where minimal board area is critical.

Part Context

This oscillator belongs to the Mercury Electronic series of quartz-based timing components. The manufacturer specializes in frequency control products including crystals and oscillators. This specific model represents a standard XO variant optimized for modern low-voltage digital electronics requiring stable clock sources.

Replacement Considerations

Direct substitutes must match the 12.463 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify equivalent electrical characteristics such as phase noise and jitter if available from alternative suppliers.
