18QHTF21-41.666667-PD

Oscillators Overview

The 18QHTF21-41.666667-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 41.666667 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) function to manage power consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic for digital interface compatibility
• Includes Standby or Power Down functionality for energy management
• Utilizes a 4-SMD No Lead surface-mount package design

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance against the manufacturer's official datasheet before procurement. Ensure the selected component matches the required 1.8V supply voltage and LVCMOS output requirements for the target application. Confirm package dimensions and thermal specifications align with the PCB layout constraints.

Oscillators Selection Notes

Select this component when a precise 41.666667 MHz clock source is required with low voltage operation. Consider the 1.8V supply constraint and the need for a standby feature. Evaluate the 4-SMD No Lead package size against available board space. Verify that LVCMOS output levels are compatible with the receiving logic inputs.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which offers various frequencies and packages. The 18QHTF21 variant specifically denotes a standard oscillator with LVCMOS outputs. The 'PD' suffix typically indicates the presence of a power-down control feature, distinguishing it from continuously running variants within the same family.

Oscillators Replacement Considerations

Consult the official Mercury Electronics replacement guide for direct substitutes. Ensure any alternative maintains the 41.666667 MHz frequency, 1.8V supply, and LVCMOS output type. Verify package compatibility if swapping with other manufacturers.
