18QHTF21-8.045715-OE

Overview

The 18QHTF21-8.045715-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 8.045715 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications with a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable pin functionality for power management
• Utilizes a leadless SMD package for space-constrained designs

Applications

• General clock signal generation in embedded systems
• Timing reference for microcontrollers operating at 1.8V
• Data communication interfaces requiring precise frequency stability

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliability during assembly.

Selection Notes

Select this component when a precise 8.045715 MHz clock source is required for 1.8V logic circuits. Consider the enable/disable feature if power efficiency is critical for the application. Evaluate the size of the 4-SMD package against available board real estate. Compare performance metrics such as phase noise and stability against other oscillators in the Mercury Electronics portfolio if stricter timing specifications are needed.
