18QHTF21-75.350-OE

Overview

The 18QHTF21-75.350-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.35 MHz and utilizes LVCMOS output logic. The device functions on a 1.8V supply voltage and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features enable and disable control functionality
• Utilizes a surface-mount 4-SMD no lead package

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a precise 75.35 MHz clock source is required for low-voltage digital applications. The LVCMOS output ensures compatibility with standard logic families. Consider the enable/disable pin if power management or clock gating is necessary within the design architecture.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, characterized by small form factor surface-mount packaging. The series typically offers various frequency options within a standardized physical envelope, allowing designers to maintain consistent board layouts while adjusting clock speeds for different application needs.

Replacement Considerations

Direct substitutes include other 75.35 MHz XO components with identical 1.8V LVCMOS specifications and 4-SMD no lead footprints. Verify electrical parameters such as phase noise and jitter against the original datasheet to ensure functional equivalence.
