18QHTF21-50.0467-OE

Overview

The 18QHTF21-50.0467-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 50.0467 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

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

Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

Procurement Notes

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

Selection Notes

Select this component when a 50.0467 MHz clock source is required with low-voltage operation. The LVCMOS output is appropriate for standard digital logic families. Consider the enable/disable feature if power management or clock gating is necessary within the design. The small form factor supports high-density board layouts.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard oscillators for various electronic applications.
