18QHTF21-66.088561-OE

Overview

The 18QHTF21-66.088561-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 66.088561 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

• General-purpose clock signal generation
• Digital system timing references
• Embedded electronics requiring stable frequency sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the enable pin logic levels are compatible with your controlling microcontroller or FPGA to guarantee proper operation of the disable feature.

Selection Notes

Select this component when a precise 66.088561 MHz clock source is required in a low-profile form factor. Consider the LVCMOS output swing and the 1.8V operating voltage as primary constraints. Evaluate the thermal performance and stability needs relative to the standard XO specifications provided in the official datasheet.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series offers various frequencies with consistent packaging and electrical characteristics. The 'OE' suffix typically denotes a specific ordering or configuration variant within the manufacturer's catalog structure.

Replacement Considerations

Direct substitutes must match the 66.088561 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical parameters such as phase noise and jitter if specified in the original design documentation.
