QT532G-14.31818MAGD-T

Overview

The QT532G-14.31818MAGD-T is a surface-mount crystal oscillator manufactured by QST, operating at a fundamental frequency of 14.31818 MHz. This component belongs to the QT532G series and features an AAE suffix indicating ±30 ppm frequency stability within the -20°C to +70°C temperature range. It utilizes a 12 pF load capacitance and exhibits a maximum equivalent series resistance (ESR) of 50 Ohms. The device is housed in a compact 2-SMD, No Lead package, designed for integration into space-constrained electronic circuits requiring precise timing references.

Feature Summary

• Provides stable oscillation with ±30 ppm frequency tolerance across industrial temperature ranges
• Utilizes a lead-free 2-SMD footprint for automated surface-mount assembly processes
• Operates with a standard 12 pF load capacitance for compatibility with common MCU interfaces

Applications

• Microcontroller unit clock sources
• Wireless networking equipment timing
• Industrial HMI display systems

Procurement Notes

Verify the specific suffix code against official QST documentation to confirm temperature range and stability class. Ensure the load capacitance matches the target circuit design requirements. Confirm package dimensions align with PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a 14.31818 MHz reference is required with moderate stability. The ±30 ppm specification suits applications less sensitive to drift than high-end communications. Verify that the 50 Ohm ESR limit is compatible with the oscillator circuit's drive level specifications.

Part Context

This part is part of the QT532G series of crystals from QST. The series offers various stability options denoted by suffix letters, such as A for ±30 ppm or G for ±50 ppm over extended temperatures. The 14.31818 MHz frequency is commonly used in video and audio processing applications due to its relationship with standard sampling rates.

Replacement Considerations

Cross-reference with other manufacturers offering 14.31818 MHz crystals in 2-SMD packages. Ensure replacement parts match the 12 pF load capacitance and 50 Ohm ESR limits. Verify that alternative components meet the same ±30 ppm stability requirement over the -20°C to +70°C range.
