18QHTF21-123.750-OE

Overview

The 18QHTF21-123.750-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 123.75 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

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

Applications

• Digital signal processing systems
• Communication equipment timing
• Embedded system clock generation

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 PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a 123.75 MHz clock source with LVCMOS outputs is required. Consider the 1.8V operating voltage and the enable/disable pin utility for power management strategies. Evaluate the thermal performance and size constraints of the 4-SMD package relative to the available board space.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies within a small form factor. The suffix OE indicates specific packaging or handling characteristics defined by the manufacturer for this particular model variant.

Replacement Considerations

Direct substitutes must match the 123.75 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical specifications before substitution.
