18QHTF21-10.680-OE

Overview

The 18QHTF21-10.680-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.68 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, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports enable and disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Housed in a 4-SMD no lead surface mount package

Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant matches the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the LVCMOS output level is compatible with the receiving logic inputs before finalizing procurement orders.

Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 1.8V logic systems. The 4-SMD package offers space efficiency compared to larger through-hole alternatives. Consider the enable pin feature if dynamic power control is necessary for the application design.

Part Context

This part belongs to the 18QHTF series of standard crystal oscillators from Mercury Electronics. The series typically covers various frequencies and voltages, providing standardized timing solutions for modern electronic devices. The 'OE' suffix indicates a specific configuration within this product line.

Replacement Considerations

Direct substitutes include other 10.68 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications before swapping components.
