18QHTF21-14.284-OE

Oscillators Overview

The 18QHTF21-14.284-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 14.284 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features an enable/disable control pin for power management flexibility. It is housed in a compact 4-SMD, no-lead package designed for surface-mount assembly. This component serves as a precise clock source for digital circuits requiring stable timing signals within the specified electrical parameters.

Oscillators Feature Summary

• LVCMOS output logic provides compatible signal levels for standard digital interfaces
• Integrated enable/disable functionality allows for active power state control
• Compact 4-SMD no-lead package facilitates automated surface-mount placement

Oscillators Applications

• Clock generation for embedded microprocessor systems
• Timing reference for communication interface modules
• Synchronization source for digital signal processing circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors. Cross-reference the enable pin polarity with the controlling logic level to guarantee proper operation.

Oscillators Selection Notes

Select this oscillator when a low-voltage 1.8V supply is available and LVCMOS compatibility is required. The enable feature makes it suitable for battery-powered or power-sensitive applications. Consider the physical size constraints of the 4-SMD package during layout planning. Verify that the 14.284 MHz frequency meets the exact timing needs of the application without requiring additional dividers.

Oscillators Part Context

This component belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized small outline package. The series supports both standard and spread-spectrum options across different supply voltages. The -OE suffix typically denotes a specific ordering configuration or packaging variant within the manufacturer's catalog structure.

Oscillators Replacement Considerations

Direct substitutes must match the 14.284 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify equivalent electrical specifications including current consumption and enable logic behavior. Alternative parts from other manufacturers require careful validation of pinout compatibility and thermal characteristics.
