18QHTF21-7.675-OE

Overview

The 18QHTF21-7.675-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.675 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control functionality. It is housed in a compact 4-SMD, No Lead package.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control functionality
• Compact 4-SMD No Lead surface mount package

Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your power management architecture. Ensure the 4-SMD No Lead footprint matches your PCB layout constraints to guarantee proper assembly and electrical connection.

Selection Notes

Select this component when a precise 7.675 MHz timing source is required for low-power applications. The LVCMOS output ensures compatibility with standard digital logic families. Consider the enable/disable feature if power management or clock gating is necessary for the target application's operational efficiency.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies within the XO category. This specific model provides a fixed 7.675 MHz output, distinguishing it from other variants in the lineup that may offer different frequencies or packaging options.

Replacement Considerations

Direct substitutes must match the 7.675 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical specifications before substitution.
