18QHTF21-13.53053-OE

Overview

The 18QHTF21-13.53053-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.53053 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 with dimensions of 2.0x1.6mm. The component supports lead-free manufacturing processes and is intended for surface-mount applications requiring precise clock signals.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable control functionality
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage and package specifications. Confirm that the required operating temperature range aligns with the datasheet limits. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the mechanical drawings. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for the target application. Consider the LVCMOS output level compatibility with downstream logic circuits. Evaluate the physical size constraints to ensure the 2.0x1.6mm package fits within the design layout. Verify that the enable/disable feature is necessary for power management strategies in the final product.

Part Context
