18QHTF21-11.520-OE

Overview

The 18QHTF21-11.520-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 11.52 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD surface-mount package, designed for applications requiring precise timing signals in low-voltage digital circuits.

Feature Summary

• Integrates LVCMOS output logic for direct interfacing with digital components
• Supports active enable and disable states for power management
• Utilizes a lead-free 4-SMD surface-mount form factor

Applications

• Digital signal processing systems
• Communication interface modules
• Microcontroller clock sources

Procurement Notes

Verify the specific suffix 'OE' against manufacturer documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the 1.8V supply requirement aligns with target circuit design constraints before procurement.

Selection Notes

Select this component when a stable 11.52 MHz reference is required for LVCMOS-compatible logic families. Consider the 1.8V operating voltage and small 4-SMD footprint as primary selection drivers for space-constrained designs.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequency options within a consistent 4-SMD package, providing designers with standardized timing solutions across different application frequencies.

Replacement Considerations

Cross-reference other variants within the 18QHTF21 series for identical package and voltage specifications if frequency adjustments are permissible. Verify pin compatibility and electrical characteristics with alternative manufacturers offering similar LVCMOS XO devices.
