18QHTF21-8.600-OE

Overview

The 18QHTF21-8.600-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 86.6 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features enable/disable control functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.

Feature Summary

• Standard clock oscillator with LVCMOS output interface
• Integrated enable and disable control capability
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system power rails. Ensure the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues or damage.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 86.6 MHz clock source. The LVCMOS output is suitable for standard digital logic families. Consider the small form factor of the 4-SMD package for space-constrained designs requiring reliable surface-mount assembly.

Part Context

This part belongs to the Mercury Electronic XO series, which provides quartz-based timing solutions. Mercury Electronics specializes in frequency control products including crystals, oscillators, and filters, leveraging decades of manufacturing expertise in Taiwan to produce reliable timing components for various electronic applications.

Replacement Considerations

Direct substitutes must match the 86.6 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before swapping. Generic replacements may differ in phase noise or load capacitance requirements.
