18QHTF21-2.8224-OE

Oscillators Overview

The 18QHTF21-2.8224-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 2.8224 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the 4-SMD package footprint matches the PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature offers power management flexibility compared to always-on oscillators. Consider the small form factor of the 4-SMD package for space-constrained designs where traditional through-hole or larger SMD oscillators cannot fit.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a manufacturer specializing in quartz crystals and oscillators. The series typically covers various frequencies within the standard XO category. Mercury Electronics is recognized as a pioneer in Taiwan's quartz industry, providing frequency control solutions for electronic components.

Oscillators Replacement Considerations

Direct replacements must match the 2.8224 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if specified in the original design documentation.
