18QHTF21-6.760-OE

Overview

The 18QHTF21-6.760-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 6.76 MHz and utilizes an LVCMOS output interface. The device is designed for operation with a supply voltage of 1.8V and includes enable/disable functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable and disable control capability
• Compact 4-SMD no-lead surface mount packaging

Applications

• General purpose digital circuit timing
• Embedded system clock generation
• Consumer electronics signal synchronization

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead footprint matches the PCB layout requirements to prevent assembly issues.

Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required for space-constrained designs. The enable/disable feature allows for power management strategies. Consider the 6.76 MHz frequency specifically for applications requiring this exact timing reference rather than standard frequencies like 8MHz or 12MHz.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, a manufacturer specializing in quartz crystals and oscillators. The series typically offers standard XO solutions with various frequency options. The -OE suffix likely denotes specific packaging or tape-and-reel configuration details as per manufacturer coding standards.

Replacement Considerations

Direct substitutes include other 6.76 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications such as load capacitance and drive strength before swapping components.
