18QHTF21-41.952-PD

Oscillators Overview

The 18QHTF21-41.952-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 41.952 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to reduce consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode for power management
• Utilizes LVCMOS output interface

Oscillators Applications

• General clock signal generation
• Embedded system timing
• Consumer electronics circuits

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 41.952 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint is compatible with the PCB layout. Check for any specific handling requirements associated with surface-mount components.

Oscillators Selection Notes

Select this component when a precise 41.952 MHz clock source is required for low-power applications. The LVCMOS output ensures compatibility with standard digital logic families. The small 2.0x1.6mm form factor is suitable for space-constrained designs. Verify temperature range requirements against the datasheet specifications before finalizing the bill of materials.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 1.8V LVCMOS package. The series provides consistent electrical characteristics across different frequency options, allowing for easy substitution within the same family while maintaining pinout and mechanical compatibility.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical package and voltage but different frequencies, provided the timing requirement changes. Cross-brand replacements must match the 4-SMD no-lead footprint, 1.8V supply, and LVCMOS output type.
