18QHTF21-115.000-OE

Overview

The 18QHTF21-115.000-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 115 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise clock signals in space-constrained electronic systems.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features an Enable/Disable pin to manage power consumption states
• Utilizes a leadless SMD package for surface-mount assembly efficiency

Applications

• General purpose clock generation in embedded systems
• Data communication interfaces requiring stable timing references
• Consumer electronics with limited board space constraints

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct voltage and package specifications. Confirm that the OE suffix corresponds to the Enable/Disable functionality required for your design. Cross-reference the part number with official Mercury Electronics datasheets to validate availability and technical parameters before finalizing procurement orders.

Selection Notes

Select this component when a 1.8V supply voltage and LVCMOS output are required for the target circuit. Ensure the PCB footprint accommodates the 2.0 x 1.6 mm no-lead package dimensions. Consider the Enable/Disable feature if power management during idle states is a system requirement. Verify thermal operating ranges align with the intended application environment.

Part Context

This oscillator belongs to the Mercury Electronics H series of surface-mount devices. The brand has over four decades of experience in quartz crystal manufacturing. The 18QHTF21 series typically offers high stability and reliability for commercial and industrial applications. Mercury Electronics is recognized as a pioneer in the Taiwanese quartz industry.

Replacement Considerations

Direct substitutes may include other 115 MHz LVCMOS oscillators from Mercury Electronics with compatible packages. Check for variants with different supply voltages or output types if system requirements change. Ensure any replacement maintains the same physical footprint and pin configuration for seamless integration.
