18QHTF21-83.328-OE

Overview

The 18QHTF21-83.328-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 83.328 MHz and utilizes LVCMOS output logic levels. The device supports an active enable/disable control function and is powered by a 1.8V supply voltage. It is housed in a compact 4-SMD, No Lead package designed for surface mount applications.

Feature Summary

• Supports Enable/Disable functionality for power management
• Utilizes LVCMOS output interface
• Compact 4-SMD No Lead package design

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller clock sources

Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm exact electrical tolerances and pinout configurations. Ensure the 1.8V supply requirement aligns with the target circuit design before procurement. Cross-reference the 4-SMD No Lead footprint dimensions with PCB layout guidelines to prevent assembly errors.

Selection Notes

Select this component when a precise 83.328 MHz clock source is required with low voltage operation. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable/disable feature if power conservation during idle states is necessary for the application.

Part Context
