18QHTF21-6.5536-OE

Overview

The 18QHTF21-6.5536-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 6.5536 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes Enable/Disable functionality for power management
• Utilizes a 4-SMD, No Lead surface-mount package

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix to confirm the enable/disable function versus standby mode variants. Ensure the supply voltage requirement matches the target circuit design. Confirm package dimensions against PCB footprint specifications prior to integration.

Selection Notes

Select this component when a 1.8V supply and LVCMOS output are required. Consider the Enable/Disable feature for power-sensitive designs. Compare with similar models like the -PD variant if standby functionality is preferred over simple enable/disable control.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series includes various frequencies and voltage options. The -OE suffix typically denotes the Enable/Disable function configuration within this product line.

Replacement Considerations

Direct substitutes may include other 1.8V LVCMOS oscillators with identical pinouts and frequencies. Verify electrical parameters and package dimensions before substitution.
