18QHTF21-54.054-OE

Oscillators Overview

The 18QHTF21-54.054-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 54.054 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.

Oscillators Feature Summary

• Generates a precise 54.054 MHz clock signal using quartz technology
• Provides LVCMOS output logic levels for digital interface compatibility
• Includes hardware enable and disable functionality for power management

Oscillators Applications

• General purpose clock generation in electronic circuits
• Timing reference for digital systems requiring standard XO performance
• Embedded applications utilizing 1.8V logic families

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a standard frequency of 54.054 MHz is required with low-voltage operation. The LVCMOS output is suitable for direct interfacing with CMOS-compatible digital inputs. Consider the enable/disable feature if dynamic power saving or clock gating is necessary within the application architecture.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD Oscillator series, specifically designed for surface-mount technology. The model number indicates a standard XO type with a 1.8V operating voltage. It is distinct from differential oscillators or crystals within the same manufacturer portfolio due to its single-ended LVCMOS output configuration.

Oscillators Replacement Considerations

Direct substitutes must match the 54.054 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical parameters such as phase noise and jitter if available in official datasheets.
