18QHTF21-13.4102-OE

Overview

The 18QHTF21-13.4102-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.4102 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features integrated enable/disable control functionality
• Utilizes a compact 4-SMD no lead surface mount package

Applications

• Digital signal processing systems
• Communication equipment timing circuits
• Embedded system clock generation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your power management architecture. Ensure the 4-SMD no lead footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The enable/disable feature allows for power management strategies in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs where standard through-hole or larger SMD oscillators do not fit.

Part Context

This part belongs to the Mercury Electronic XO series, which specializes in quartz-based frequency control products. The manufacturer has extensive experience in Taiwan's crystal industry since 1973. This specific model represents their standard oscillator line, offering reliable performance for general-purpose timing applications in consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes within the same Mercury Electronic family sharing identical pinout and electrical characteristics. Verify if alternative brands offer compatible LVCMOS outputs with matching 1.8V supply requirements. Ensure any replacement maintains the 4-SMD no lead package dimensions for seamless board integration.
