18QHTF21-13.224-OE

Overview

The 18QHTF21-13.224-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.224 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Produces a stable 13.224 MHz clock signal using quartz technology
• Utilizes LVCMOS output logic for digital circuit compatibility
• Includes hardware enable and disable functionality for power management

Applications

• General purpose clock generation for embedded systems
• Timing reference for digital communication interfaces
• Clock source for microcontroller or FPGA circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs. Consider the LVCMOS output type if interfacing directly with standard digital logic families without additional buffering.

Part Context

This part belongs to the H21 series of SMD oscillators from Mercury Electronics. The manufacturer has produced frequency control products since 1973 and is recognized as a pioneer in the Taiwan quartz industry. This series typically offers standard XO configurations with various frequency options.

Replacement Considerations

Cross-reference other parts within the 18QHTF21 series from Mercury Electronics for different frequencies. Verify pinout and electrical characteristics against alternative manufacturers' offerings to ensure functional equivalence in terms of voltage, output type, and package dimensions.
