18QHTF21-108.108-OE

Overview

The 18QHTF21-108.108-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 108.108 MHz and utilizes LVCMOS output logic. The component is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Includes hardware enable and disable control functionality
• Utilizes a surface-mount 4-SMD No Lead package for space-constrained designs

Applications

• General clock signal generation in embedded systems
• Timing reference for digital communication interfaces
• Clock source for microcontroller or FPGA circuits

Procurement Notes

Verify the specific suffix 'OE' to confirm the presence of the enable/disable pin configuration, as this distinguishes it from standard variants without control inputs. Ensure the operating voltage matches the 1.8V requirement of the target circuit design. Confirm that the 2.0x1.6 mm footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when a precise 108.108 MHz timing reference is required within a low-voltage 1.8V system architecture. The choice is appropriate for applications necessitating active control over the oscillator state via an enable pin. Consider the small form factor suitable for dense board layouts where larger packages are not feasible.

Part Context

This part belongs to the Mercury Electronics XO series, which provides stable frequency references for electronic circuits. The model number indicates a 1.8V operation and a specific 108.108 MHz frequency. The 'OE' suffix denotes the inclusion of an enable feature, differentiating it from basic oscillators lacking control pins.

Replacement Considerations

Direct substitutes include other 108.108 MHz LVCMOS oscillators with identical 1.8V supply requirements and compatible 4-SMD No Lead footprints. Verify that any replacement part supports the enable/disable control function if this feature is critical to the system design.
