18QHTF22-71.4376-PD

Oscillators Overview

The 18QHTF22-71.4376-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 71.4376 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down (PD) control function for standby mode management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.5mm x 2.0mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy efficiency
• Utilizes LVCMOS output interface

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific suffix 'PD' to confirm power-down functionality against the datasheet. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm the 2.5x2.0mm footprint matches the PCB layout constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 71.4376 MHz frequency is required within space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital systems. The power-down feature allows for active power management strategies in battery-operated applications.

Oscillators Part Context

This part belongs to the 18QHTF22 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, with the 'PD' suffix specifically denoting the inclusion of a power-down control pin for enhanced power management capabilities.

Oscillators Replacement Considerations

Direct substitutes must match the 71.4376 MHz frequency, 1.8V supply, LVCMOS output, and 2.5x2.0mm package. Verify that any alternative also includes the power-down feature if that functionality is critical to the design.
