18QHTF21-11.2896-OE

Overview

The 18QHTF21-11.2896-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.2896 MHz with an LVCMOS output logic level. The device requires 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

• Supports enable and disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed as a precision timing component for stable clock generation

Applications

• Telecommunications equipment requiring precise timing signals
• Networking devices utilizing standard clock frequencies
• Audio and video equipment needing accurate synchronization

Procurement Notes

Verify the specific suffix 'OE' corresponds to the enable feature when sourcing replacements. Confirm the operating temperature range and load capacitance requirements match the target circuit design. Ensure the 1.8V supply voltage aligns with the system's power rails before integration.

Selection Notes

Select this component when a 11.2896 MHz clock signal is required with low voltage operation. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Consider the enable pin requirement if dynamic power saving is necessary for the application.

Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'OE' suffix indicates the inclusion of an output enable control, distinguishing it from standard continuous-output variants within the same package family.

Replacement Considerations

Direct substitutes include other 11.2896 MHz XO components with LVCMOS outputs and 1.8V operation. Verify that replacement parts support the same 2.0x1.6mm SMD package and have compatible enable logic levels to ensure seamless integration without circuit modification.
