18QHTF21-13.498-OE

Overview

The 18QHTF21-13.498-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.498 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• 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 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 PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable pin allows for power management in battery-operated devices. Consider the small form factor for space-constrained designs. Verify temperature stability needs as standard oscillators may have wider drift ranges compared to TCXO variants.

Part Context

This part belongs to the Mercury Electronics XO series, focusing on standard frequency control solutions. Mercury Electronics has produced timing components since 1973, specializing in quartz crystals and oscillators. This model represents their surface-mount oscillator lineup, targeting modern electronics requiring reliable, low-profile timing elements.

Replacement Considerations

Direct substitutes include other 13.498 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Ensure voltage levels and pinout configurations match exactly. Cross-reference electrical parameters such as phase noise and jitter if high precision is required.
