18QHTF21-26.800-OE

Oscillators Overview

The 18QHTF21-26.800-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 26.8 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package designed for surface-mount assembly.

Oscillators Feature Summary

• LVCMOS output interface for digital circuit compatibility
• Integrated enable and disable control pin
• Surface-mount 4-SMD no-lead package design

Oscillators Applications

• Digital clock signal generation
• Microcontroller system timing
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm pinout configuration and electrical tolerances. Ensure the 1.8V supply requirement matches the target system voltage. Confirm the 4-SMD no-lead footprint dimensions align with the PCB layout constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 26.8 MHz reference is required for low-voltage digital systems. The LVCMOS output simplifies interfacing with standard logic families. Consider the enable feature if power conservation during idle states is necessary for the application design.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides stable frequency references for electronic circuits. The company specializes in quartz-based frequency control products, including crystals and oscillators, serving various industrial and consumer electronics markets globally.

Oscillators Replacement Considerations

Cross-reference the 18QHTF21-26.800-PD variant from the same manufacturer family. Verify that the PD suffix does not alter the electrical characteristics or package dimensions compared to the OE version before substitution.
