18QHTF21-123.457-OE

Overview

The 18QHTF21-123.457-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 123.457 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable and disable functionality for power management
• Utilizes a leadless SMD package for surface-mount assembly

Applications

• General clock signal generation
• Digital system timing references
• Embedded electronics circuits

Procurement Notes

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

Selection Notes

Select this component when a 123.457 MHz clock source is required with low-voltage operation. Consider the LVCMOS output level for direct interfacing with compatible logic families. Evaluate the enable pin utility for systems requiring dynamic power conservation or clock gating capabilities during idle states.

Part Context

This model belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The suffix OE indicates a specific configuration variant within the manufacturer's product line, distinguishing it from other frequency options in the same package type.

Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical electrical parameters but different frequencies, such as the 18QHTF21-125.000-OE, provided the frequency difference is acceptable for the application.
