18QHTF21-13.4916-OE

Overview

The 18QHTF21-13.4916-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.4916 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Integrates enable/disable functionality for efficient power management
• Delivers stable LVCMOS output signals for digital circuit interfacing
• Utilizes a miniature 4-SMD no-lead package for space-constrained designs

Applications

• Portable electronic devices requiring low-power timing sources
• Embedded systems utilizing LVCMOS-compatible processors
• Consumer electronics with strict size limitations

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure that the 1.8V supply voltage aligns with your target platform's power rails. Confirm that the enable pin logic levels are compatible with your microcontroller or GPIO outputs to guarantee proper activation and deactivation sequences during operation.

Selection Notes

Select this component when a 13.4916 MHz clock signal is required within a 2.0x1.6 mm footprint. Consider the 1.8V operating voltage and LVCMOS interface compatibility with your downstream logic. The enable/disable feature makes it suitable for battery-powered applications where power conservation is critical compared to continuously running oscillators.

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 Taiwan producing crystals and oscillators.
