18QHTF21-28.375-OE

Oscillators Overview

The 18QHTF21-28.375-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 28.375 MHz. It utilizes LVCMOS output logic and supports a supply voltage of 1.8V. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications in electronic circuits requiring precise clock signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power optimization
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific part number suffix against official Mercury Electronics documentation to ensure correct voltage and logic levels. Confirm package dimensions and pinout compatibility with your PCB footprint before ordering. Request the latest datasheet from authorized distributors to validate current manufacturing specifications and environmental compliance status.

Oscillators Selection Notes

Select this component when a 28.375 MHz clock source with LVCMOS outputs is required. Ensure the system operates at 1.8V and requires enable/disable control. Verify that the 4-SMD no-lead package fits the available board space. Compare against other Mercury series oscillators if different frequencies or voltages are needed.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics XO (Standard) series, which provides basic clock solutions. The 18QHTF21 prefix indicates the specific form factor and performance class within their SMD oscillator lineup. It is distinct from TCXO or VCXO variants, offering fixed frequency stability without temperature compensation or voltage control.

Oscillators Replacement Considerations

Direct substitutes must match the 28.375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check Mercury part numbers like 18QHTF21-28.375-PD for similar series options, but verify voltage differences. Cross-brand replacements require identical electrical parameters and mechanical dimensions.
