18QHTF21-41.667-PD

Oscillators Overview

The 18QHTF21-41.667-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 41.667 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) control function to manage power consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic levels
• Includes Standby mode for power down capability
• Utilizes a surface-mount 4-SMD No Lead package

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Portable devices utilizing low-power oscillator solutions

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 footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet.

Oscillators Selection Notes

Select this component when a precise 41.667 MHz timing source is required within space-constrained designs. The 1.8V supply requirement makes it suitable for modern low-voltage digital logic families. The integrated standby feature allows for dynamic power management in battery-operated applications. Consider the small 2.0x1.6mm form factor for high-density board layouts.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage crystal oscillators. The series typically offers various frequency options within a standardized small outline package. The 'PD' suffix indicates the inclusion of a power-down pin or functionality, distinguishing it from basic continuous-operation variants.

Oscillators Replacement Considerations

Direct replacements must match the 41.667 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify compatibility with existing PCB footprints and thermal requirements. Consult manufacturer cross-reference lists for equivalent parts from other suppliers.
