18QHTF21-6.800-OE

Overview

The 18QHTF21-6.800-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 6.8 MHz and utilizes LVCMOS output logic levels. The device is designed for operation with a supply voltage of 1.8V and includes an integrated enable/disable control function to manage power consumption. It is housed in a compact 4-SMD, no-lead package suitable for surface-mount assembly.

Feature Summary

• Integrates enable/disable functionality for power management
• Provides LVCMOS output signal compatibility
• Utilizes low-profile surface-mount packaging

Applications

• Embedded system clock generation
• Digital signal processing timing references
• Communication interface synchronization

Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct voltage and package specifications. Confirm that the OE suffix aligns with the required enable pin configuration and output drive strength. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when a precise 6.8 MHz reference is required with low-voltage operation. Ensure the design supports LVCMOS logic thresholds and accommodates the enable/disable control signal. Verify thermal and mechanical constraints match the 4-SMD no-lead footprint requirements for the target PCB layout.

Part Context

This oscillator belongs to Mercury Electronics' standard XO series, which focuses on quartz-based timing solutions. The manufacturer specializes in frequency control products including crystals, oscillators, and filters, leveraging decades of experience in Taiwan's electronics manufacturing sector.

Replacement Considerations

Consult official cross-reference lists for compatible alternatives. Ensure substitute parts match the 6.8 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions.
