18QHTF21-27.5875-OE

Oscillators Overview

The 18QHTF21-27.5875-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 27.5875 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

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

Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the OE suffix with manufacturer documentation to confirm availability and lead times through authorized distributors.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The small 4-pin form factor makes it suitable for space-constrained designs. Consider the enable pin feature if power management or clock gating is necessary for the application. Verify that the 27.5875 MHz frequency meets the target system's timing specifications.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series typically offers various frequencies within a small footprint. Mercury Electronics specializes in quartz crystals and timing devices, providing solutions for consumer electronics and industrial applications. This specific model represents a standard XO variant with enable capability.

Oscillators Replacement Considerations

Direct replacements must match the 27.5875 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check datasheets for compatible parts from other manufacturers offering identical electrical characteristics and pinout configurations to ensure seamless integration without PCB redesign.
