18QHTF21-116.625-OE

Overview

The 18QHTF21-116.625-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 116.625 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component is designed for standard clock signal generation applications requiring precise timing.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features active enable and disable control functionality for power optimization
• Utilizes a leadless surface-mount package design for space-constrained layouts

Applications

• Clock signal generation for high-speed digital circuits
• Timing reference sources in communication equipment
• System clock inputs for embedded processors

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the exact enable/disable configuration and tolerance specifications. Ensure the required operating temperature range aligns with the datasheet limits for the intended environment. Cross-reference the package outline drawing to confirm mechanical fit within the assembly footprint.

Selection Notes

Select this component when a 1.8V supply voltage and LVCMOS output are required for the target circuit. Consider the 2.0x1.6mm package size for board space limitations. Evaluate the need for the enable/disable pin if power management during idle states is a system requirement. Confirm that the 116.625 MHz frequency matches the system clock architecture.

Part Context

This part belongs to the Mercury Electronics SMD oscillator series, which focuses on small form-factor timing solutions. The manufacturer has extensive experience in quartz crystal production since 1973. This specific model represents a standard XO variant designed for general-purpose clocking needs in modern electronic devices.

Replacement Considerations

Direct substitutes include other 116.625 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pinout compatibility and electrical parameters before swapping. Alternative part numbers such as those with different suffixes may offer varied tolerances or temperature ranges.
