18QHTF21-13.567188-OE

Overview

The 18QHTF21-13.567188-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.567188 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Integrates LVCMOS output interface for digital signal compatibility
• Features enable/disable functionality for power optimization
• Utilizes low-profile SMD package for space-constrained designs

Applications

• Consumer electronics timing circuits
• Portable communication devices
• Embedded system clock generation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. 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 stable 13.567188 MHz reference is required for LVCMOS-compatible digital interfaces. Consider the 1.8V operating voltage constraint and the need for active enable/disable control. The small 2.0x1.6mm form factor makes it appropriate for high-density board layouts where space efficiency is critical compared to larger oscillator packages.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has decades of experience in producing crystals, oscillators, and filters. This specific model represents a standard XO variant designed for general-purpose timing applications within the consumer and industrial electronics sectors.

Replacement Considerations

Direct substitutes must match the 13.567188 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical parameters such as frequency stability and phase noise if available in public datasheets.
