18QHTF21-12.8832-OE

Overview

The 18QHTF21-12.8832-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 12.8832 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

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Utilizes a leadless SMD package for space-constrained designs

Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded microcontroller clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable pin logic levels are compatible with your controlling GPIO to prevent unintended oscillation states during operation.

Selection Notes

Select this component when a low-voltage 1.8V supply is available and LVCMOS outputs are required. The 12.8832 MHz frequency is suitable for specific baud rate generation or clock division needs. Consider the 4-SMD package size if board real estate is limited compared to larger through-hole alternatives.

Part Context

This part belongs to the QHTF series of quartz-based oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though exact details require datasheet confirmation. It serves as a stable timebase for electronic circuits.

Replacement Considerations

Direct substitutes must match the 12.8832 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead footprint. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications to ensure seamless integration without circuit redesign.
