18QHTF21-47.432728-PD

Oscillators Overview

The 18QHTF21-47.432728-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 47.432728 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package suitable for surface mount applications.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby control for power management
• RoHS compliant construction
• Moisture Sensitivity Level 1 classification

Oscillators Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD package footprint matches the PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 47.432728 MHz clock source is required for LVCMOS-compatible circuits. The choice depends on the necessity for low-power standby functionality and the availability of a 1.8V power rail. Consider the physical size of the 4-SMD package relative to other available oscillator options in the QHTF series.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The suffix PD indicates the presence of a power-down pin, distinguishing it from OE (Enable/Disable) variants within the same family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 models with identical 47.432728 MHz frequency, 1.8V operation, and LVCMOS output. Verify package dimensions and pinout compatibility before replacing.
