18QHTF21-72.2676-OE

Overview

The 18QHTF21-72.2676-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 72.2676 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes enable/disable functionality. 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 capability
• Surface-mount 4-SMD no lead package design

Applications

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

Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the target design requirements. Ensure the 1.8V supply voltage aligns with the system power rails before procurement.

Selection Notes

Select this component when a low-profile 4-SMD oscillator is required for 1.8V logic systems. Consider the enable/disable feature if power management during idle states is necessary. Verify that the 72.2676 MHz frequency meets the exact timing specifications of the application.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The 18QHTF21 series typically offers reliable performance for general electronic applications requiring stable clock signals in small form factors.

Replacement Considerations

Consult official substitution lists for compatible oscillators with matching frequency, voltage, and package dimensions. Cross-reference with other Mercury Electronics models or industry-standard equivalents only if verified by the manufacturer.
