18QHTF21-13.581445-OE

Overview

The 18QHTF21-13.581445-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 13.581445 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports Enable/Disable functionality for active power control
• Utilizes LVCMOS output logic for digital interface compatibility
• Operates on a 1.8V supply voltage

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• 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 4-SMD No Lead package dimensions fit within your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics to guarantee reliable operation under intended environmental conditions.

Selection Notes

Select this component when a low-voltage 1.8V clock source is required for LVCMOS-compatible circuits. The Enable/Disable pin allows for dynamic power management, making it suitable for battery-operated or energy-efficient designs. Consider the 4-SMD No Lead form factor for high-density board layouts where space is limited compared to through-hole alternatives.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard crystal oscillators. The series offers various frequencies and voltage options, all sharing a common compact SMD footprint. Mercury Electronics specializes in quartz frequency control products, providing stable timing solutions for consumer electronics and industrial applications.

Replacement Considerations

Direct substitutes must match the 13.581445 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify that any replacement part supports the same Enable/Disable control scheme to maintain existing power management functionality without circuit redesign.
