18QHTF21-13.396875-OE

Overview

The 18QHTF21-13.396875-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.396875 MHz and utilizes an LVCMOS output signal type. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports Enable/Disable functionality for active power control
• Delivers LVCMOS output signal compatibility
• Operates on a 1.8V supply voltage

Applications

• Digital logic circuits requiring precise clock synchronization
• Embedded systems utilizing low-voltage microcontrollers
• Communication interfaces needing stable frequency references

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the Enable/Disable function. Ensure the 1.8V operating voltage aligns with target circuit designs. Confirm the 4-SMD No Lead footprint matches PCB layout requirements before ordering.

Selection Notes

Select this component when a 13.396875 MHz reference is required with low-power standby capabilities. The LVCMOS interface suits standard digital logic families. Consider the 1.8V requirement for compatibility with modern low-voltage processors and memory devices.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and packages. The '-OE' suffix specifically denotes the enable/disable capability, distinguishing it from continuous-output variants like the '-PD' or standard models within the same family.

Replacement Considerations

Cross-reference with other 13.396875 MHz LVCMOS oscillators featuring 1.8V operation and enable pins. Verify pinout compatibility and thermal characteristics before substituting.
