18QHTF21-114.240-OE

Overview

The 18QHTF21-114.240-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 114.24 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features integrated enable and disable control functionality to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated enable/disable control pin for power management
• Compact 4-SMD no-lead surface mount package design

Applications

• Digital communication systems requiring precise clock signals
• Embedded processing units needing stable timing references
• Consumer electronics with space-constrained layouts

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper soldering and electrical connection.

Selection Notes

Select this component when a 114.24 MHz frequency is required alongside low-power operation capabilities. The LVCMOS output makes it suitable for direct interfacing with standard digital logic families. Consider the enable/disable feature if dynamic power saving is necessary for the application. Verify environmental stability requirements match the standard grade specifications provided by the manufacturer.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor timing solutions. The series typically offers various frequency options within a standardized 4-pin SMD package. This specific model provides a high-frequency option optimized for modern high-speed digital interfaces while maintaining a low profile for dense board layouts.

Replacement Considerations

Direct replacements must match the 114.24 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check for equivalent part numbers from Mercury Electronics or other manufacturers offering identical electrical characteristics and pinout configurations to ensure functional interchangeability.
