18QHTF21-13.550-OE

Overview

The 18QHTF21-13.550-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.55 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage 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

• Supports enable and disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Available in hermetic ceramic leadless SMD packages

Applications

• Timing and clock signal generation in electronic devices
• General purpose timing applications requiring stable frequencies
• Embedded systems utilizing low voltage logic interfaces

Procurement Notes

Verify the specific frequency tolerance and stability specifications against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB design requirements to guarantee proper soldering and mechanical stability during operation.

Selection Notes

Select this component when a precise 13.55 MHz clock source is required within a low-profile surface-mount constraint. The choice is appropriate for designs necessitating active control over the oscillator state via the enable pin. Consider the operating temperature range and load capacitance requirements to ensure compatibility with the connected circuitry and environmental conditions.

Part Context

This part belongs to the QHTF series from Mercury Electronics, which offers various hermetic ceramic leadless SMD packages. The series supports a broad frequency range from 1.0 MHz to 200 MHz across different supply voltages. This specific model represents a standard XO variant optimized for compact electronic assemblies requiring reliable timing signals.

Replacement Considerations

Direct substitutes include other variants within the 18QHTF21 series such as 18QHTF21-13.513-OE or 18QHTF21-13.558-OE, provided the frequency difference is acceptable. Cross-reference with other manufacturers offering 2.0x1.6mm LVCMOS oscillators if form factor compatibility is the primary constraint.
