18QHTF21-64.667-OE

Overview

The 18QHTF21-64.667-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 64.667 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

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

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 ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics to guarantee reliable operation within your intended environment.

Selection Notes

Select this component when a low-voltage 1.8V supply is available and LVCMOS outputs are required. Consider the 4-SMD package size for space-constrained designs. Evaluate the need for an enable pin to manage power consumption during idle states. Compare performance metrics such as phase noise and stability if high-precision timing is critical for the application.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes a specific packaging or tape-and-reel configuration. Mercury Electronics specializes in quartz crystals and frequency control products, providing solutions for diverse electronic industries.

Replacement Considerations

Direct substitutes must match the 64.667 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications. Alternative parts from other manufacturers may require adapter footprints or level shifting if voltage levels differ.
