18QHTF21-50.044667-OE

Overview

The 18QHTF21-50.044667-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 50.044667 MHz and utilizes 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 with dimensions of 2.0mm x 1.6mm. The component is designed for standard applications requiring precise timing signals within electronic circuits.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features enable and disable control capabilities
• Utilizes a compact surface-mount package design

Applications

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

Procurement Notes

Verify the specific frequency tolerance and stability requirements against application needs. Confirm that the 1.8V supply voltage aligns with the target system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Check for any specific operating temperature range limitations required by the environment.

Selection Notes

Select this component when a 50.044667 MHz clock source is required with LVCMOS outputs. Consider the 1.8V supply constraint and the small form factor. Evaluate if the enable/disable feature is necessary for power management. Compare against other frequencies in the 18QHTF21 series if exact frequency matching is not critical.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard crystal oscillators. The series offers various frequencies with LVCMOS outputs and 1.8V operation.
