18QHTF21-18.2912-OE

Oscillators Overview

The 18QHTF21-18.2912-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 18.2912 MHz and utilizes LVCMOS output logic levels. 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 2.0x1.6mm, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Integrates an enable/disable function for flexible power control
• Delivers standard LVCMOS output signals
• Utilizes a small form factor SMD package

Oscillators Applications

• Timing and clock signal generation in electronic devices
• Embedded systems requiring precise frequency references
• Consumer electronics with space constraints

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 18.2912 MHz frequency. The integrated enable pin offers advantages in battery-powered designs where power conservation is critical. Consider the physical size constraints of the 2.0x1.6mm package when evaluating board space availability compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic. The series typically features various frequencies and voltage options within a standardized small outline package. The suffix OE indicates the presence of an enable pin, distinguishing it from standard continuous-output variants within the same family line.

Oscillators Replacement Considerations

Direct substitutes must match the 18.2912 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent enable functionality and electrical characteristics to ensure compatibility without redesigning the host circuitry.
