18QHTF21-13.501-OE

Overview

The 18QHTF21-13.501-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.501 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• LVCMOS output logic compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• Timing and clock signal generation in electronic devices
• Low-voltage digital system synchronization
• Embedded controller clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper soldering and mechanical stability during operation.

Selection Notes

Select this component when a precise 13.501 MHz clock source is required for LVCMOS-compatible digital circuits. The integrated enable feature makes it suitable for battery-powered or power-sensitive applications where dynamic power management is necessary. Consider the operating temperature range and package size constraints relative to the available board space and thermal environment of the final assembly.

Part Context

This part belongs to the 18QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small form factor. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though exact details require datasheet confirmation. This model represents a standard XO variant optimized for general-purpose timing applications.

Replacement Considerations

Direct substitutes include other 13.501 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson or NDK. Verify pinout compatibility and electrical specifications before substitution. Cross-reference part numbers like those in the same Mercury family, ensuring voltage and enable logic match.
