18QHTF21-24.540-PD

Oscillators Overview

The 18QHTF21-24.540-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 24.54 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features a standby or power-down capability for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode to reduce power consumption during idle periods
• Designed in a small form factor surface-mount package

Oscillators Applications

• General purpose timing clock generation
• Digital signal processing circuits
• Communication equipment requiring precise frequency references

Oscillators Procurement Notes

Verify the specific suffix PD indicates the power-down feature as documented. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD no-lead package footprint aligns with the PCB layout specifications before ordering.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The integrated power-down function makes it suitable for battery-operated devices where standby current reduction is critical. Verify that the 24.54 MHz frequency meets the system clock requirements.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and supply voltages, with the PD suffix denoting the inclusion of a power-down control feature. It is designed for applications requiring reliable timing in compact electronic assemblies.

Oscillators Replacement Considerations

Check for parts with identical 24.54 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify if alternative manufacturers offer equivalent power-down functionality.
