18QHTF21-6.480-OE

Overview

The 18QHTF21-6.480-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 6.48 MHz with an LVCMOS output type. The device requires a supply voltage of 1.8V and includes Enable/Disable functionality. It features a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to 85°C. The component is housed in a compact 4-SMD, No Lead package.

Feature Summary

• Provides stable timing signals via LVCMOS output interface
• Supports power management through integrated Enable/Disable control
• Designed for operation across industrial temperature ranges

Applications

• General electronic timing circuits
• Industrial application systems
• Consumer electronics devices

Procurement Notes

Verify the specific frequency suffix matches the required system clock speed, as the model series supports various frequencies. Confirm the 1.8V supply requirement aligns with target board voltages. Ensure the 4-SMD no-lead package footprint is compatible with PCB layout constraints. Check datasheet specifications for load capacitance requirements if external components are needed.

Selection Notes

Select this component when a low-voltage 1.8V oscillator is required for space-constrained designs. The LVCMOS output is suitable for direct interfacing with digital logic. Consider the ±50ppm stability for applications not requiring high-precision timing. Verify thermal performance meets the -40°C to 85°C operational environment.
