18QHTF21-118.000-OE

Overview

The 18QHTF21-118.000-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 118.0 MHz with a supply voltage of 1.8V. The device features an OE (Enable/Disable) control function and utilizes LVCMOS output logic. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Integrated enable/disable functionality for power management
• LVCMOS output logic compatibility
• Compact surface-mount package design

Applications

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

Procurement Notes

Verify the specific suffix 'OE' confirms the enable pin configuration against your schematic requirements. Ensure the 1.8V supply voltage aligns with your target logic levels. Confirm the 118.0 MHz frequency matches the exact timing needs of the application to avoid rework.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise frequency control. The OE feature allows for dynamic power saving or clock gating. Consider the small 2.0x1.6mm footprint for space-constrained PCB layouts requiring standard LVCMOS interfaces.

Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronic. The series typically offers various frequencies and voltages. The '18' prefix indicates the 1.8V operating voltage, while '21' denotes the specific package size and pinout configuration within the product line.

Replacement Considerations

Check for parts with identical 118.0 MHz frequency, 1.8V supply, and OE functionality. Verify mechanical compatibility with the 4-SMD 2.0x1.6mm footprint. Ensure output logic remains LVCMOS to maintain electrical compatibility with downstream components.
