18QHTF21-75.360-PD

Overview

The 18QHTF21-75.360-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.360 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down mode capability. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby and power-down functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS signaling standards. The choice is driven by the need for a small form factor via the 4-SMD package. Consider the availability of the power-down feature if energy efficiency during idle states is a critical design parameter for the application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The manufacturer has decades of experience in crystal manufacturing. This series typically offers standard oscillators with various frequency options and supply voltages, catering to diverse electronic timing needs.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with matching 75.360 MHz frequency and 1.8V supply, such as 18QHTF21-75.360 without the PD suffix if power-down is not needed. Cross-reference with other manufacturers offering 4-SMD LVCMOS oscillators at 1.8V, ensuring pinout and electrical characteristics are identical.
