18QHTF21-108.0025-OE

Overview

The 18QHTF21-108.0025-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 108.0025 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features enable/disable control functionality. It is housed in a compact 4-SMD package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable and disable control capabilities for power management
• Designed as a standard XO with fixed frequency operation

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller synchronization

Procurement Notes

Verify the exact electrical specifications and pinout configuration directly from the manufacturer's official datasheet before integration. Ensure the 1.8V supply requirement aligns with your system design. Confirm that the 4-SMD package dimensions fit within your PCB layout constraints. Cross-reference the part number suffix to ensure correct packaging and variant selection.

Selection Notes

Select this component when a 108.0025 MHz reference is required with low-voltage 1.8V operation. Consider the LVCMOS output type for direct interfacing with standard digital logic families. Evaluate the enable/disable feature if dynamic power saving or clock gating is necessary for the specific application environment.

Part Context

This oscillator belongs to the Mercury Electronics SMD series, which includes various quartz-based timing solutions. The company specializes in frequency control products such as crystals, TCXOs, and oscillators. This specific model represents a standard fixed-frequency solution within their portfolio of surface-mount devices.

Replacement Considerations

Check for compatible parts with identical 108.0025 MHz frequency, 1.8V supply, and LVCMOS output. Verify package compatibility for 4-SMD footprints. Ensure equivalent enable/disable functionality if present in the original design requirements.
