18QHTF21-13.506-OE

Overview

The 18QHTF21-13.506-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.506 MHz and utilizes LVCMOS output logic. The device requires 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 2.0 x 1.6 mm.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control functionality
• Compact surface-mount package design

Applications

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

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout requirements to prevent soldering defects.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for clock generation. The LVCMOS output is suitable for standard digital logic families. Consider the small 2.0x1.6 mm footprint for space-constrained designs. Verify that the enable pin functionality meets the power management needs of the application.

Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically indicates the presence of an enable pin feature. These components are designed for general-purpose clock applications requiring precise timing.

Replacement Considerations

Direct substitutes include other 13.506 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD 2.0x1.6mm footprints. Verify electrical parameters such as load current and output swing. Check mechanical height constraints if vertical space is limited.
