18QHTF21-75.033-PD

Overview

The 18QHTF21-75.033-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a nominal frequency of 75.033 MHz. It utilizes LVCMOS output logic and functions with a 1.8V supply voltage. The device features a standby mode for power down capabilities. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby functionality for power management
• Provides LVCMOS output signal compatibility

Applications

• General electronic timing circuits
• Digital signal processing systems
• Communication equipment clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a stable 75.033 MHz reference is required for LVCMOS-compatible digital interfaces. Consider the 1.8V operating voltage if your system operates on low-power rails. The compact SMD form factor makes it suitable for space-constrained designs where traditional through-hole oscillators cannot fit.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of surface-mount crystal oscillators. The series offers various frequencies and voltage options, all sharing similar physical dimensions and output characteristics. The PD suffix typically indicates specific packaging or handling variations within the manufacturer's product line.

Replacement Considerations

Direct substitutes must match the 75.033 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics when cross-referencing with other manufacturers' offerings to ensure seamless integration without redesign.
