18QHTF21-8.467-OE

Overview

The 18QHTF21-8.467-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 8.467 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. A key functional characteristic is the inclusion of an enable/disable control pin, allowing for power management in system designs. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Feature Summary

• LVCMOS output logic interface
• Integrated enable/disable control functionality
• Compact 4-SMD no lead surface mount package

Applications

• General purpose timing clock generation
• Low voltage digital circuit synchronization
• Embedded system clock sources

Procurement Notes

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

Selection Notes

Select this component when a precise 8.467 MHz reference is required for LVCMOS-compatible circuits. The integrated enable feature makes it suitable for battery-powered or power-sensitive applications where standby current reduction is necessary. Consider the operating temperature range and size constraints relative to other available oscillators in the Mercury Electronics portfolio.

Part Context
