18QHTF21-62.8375-OE

Overview

The 18QHTF21-62.8375-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 62.8375 MHz with LVCMOS output logic. The device supports a supply voltage of 1.8V and includes enable/disable functionality. It is housed in a compact 4-SMD, No Lead package suitable for surface mount applications.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control function
• Compact 4-SMD no lead surface mount package

Applications

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

Procurement Notes

Verify the specific frequency tolerance and stability requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no lead package footprint matches the PCB layout specifications to guarantee proper assembly and electrical connection.

Selection Notes

Select this component when a precise 62.8375 MHz reference is required with low power consumption. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable pin feature if power management or clock gating is necessary within the application circuit design constraints.

Part Context

This part belongs to the 18QHTF series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The suffix OE indicates specific configuration details defined by the manufacturer for this particular frequency variant within the product line.

Replacement Considerations

Direct substitutes include other 18QHTF series parts with identical pinout and electrical characteristics but different frequencies, such as 18QHTF21-8.300-OE or 18QHTF21-30.0075-OE, provided the frequency difference is acceptable for the application.
