18QHTF21-66.008-OE

Overview

The 18QHTF21-66.008-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 66.008 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Integrates enable and disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Employs quartz-based technology for frequency stability

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 66.008 MHz
• Embedded devices utilizing 1.8V logic levels

Procurement Notes

Verify the specific suffix OE against official Mercury Electronic documentation to confirm the enable/disable feature and output type. Ensure the 1.8V supply requirement aligns with system design constraints. Confirm the 4-SMD no-lead package dimensions match PCB layout specifications before procurement.

Selection Notes

Select this component when a precise 66.008 MHz timing source is required within a low-voltage 1.8V environment. The integrated enable pin allows for dynamic power control. Consider the small 2.0x1.6 mm footprint for space-constrained designs requiring standard LVCMOS outputs.

Part Context

This oscillator belongs to the Mercury Electronic series of surface-mount devices. The brand has specialized in quartz frequency control products since 1973. This specific model represents a standard XO variant designed for modern compact electronics requiring reliable clock signals.

Replacement Considerations

The datasheet lists 18QHTF21-66.008-PD as a related variant with different suffixes. Verify if the PD suffix indicates identical electrical characteristics or functional differences before substitution.
