18QHTF21-11.24565-OE

Overview

The 18QHTF21-11.24565-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 11.24565 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 with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Provides stable clock signals via LVCMOS output interface
• Supports active enable and disable control functionality
• Designed for low-voltage operation at 1.8V
• Utilizes a compact surface-mount package suitable for space-constrained designs

Applications

• General purpose clock generation in electronic circuits
• Timing reference for digital signal processing systems
• Clock source for microcontroller-based embedded applications

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to avoid assembly issues.

Selection Notes

Select this component when a precise 11.24565 MHz timing reference is required in a small form factor. Consider the LVCMOS output compatibility with your downstream logic levels. Evaluate the enable/disable feature if power management or clock gating is necessary for your application's operational modes.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options within similar physical footprints.
