Procurement Notes

Verify the manufacturer designation on official documentation, as similar part numbers may be associated with different suppliers such as TXC. Confirm that the specific suffix 'HQ' aligns with the required load capacitance and tolerance specifications for your circuit design. Ensure the requested quantity matches the standard packaging format provided by authorized distributors to avoid handling discrepancies during assembly.

Selection Notes

Select this component when a high-stability clock source is required for microcontrollers supporting advanced UI frameworks like Qt. The 10pF load capacitance must match the oscillator circuit requirements of the target MCU. Consider the -40°C to +85°C temperature range for automotive or industrial deployments where thermal stability is critical for maintaining the specified ±30ppm frequency accuracy.

Part Context

This crystal belongs to the QT325G series from QST, characterized by its small 3.2x2.5mm package and glass-seal technology. It is commonly paired with ARM Cortex-M4/M7 based microcontrollers, such as Infineon TRAVEO T2G, which require precise timing for real-time processing and high-frame-rate display rendering in embedded applications.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 48.213333 MHz crystals in 325G packages. Verify that any substitute maintains the 10pF load capacitance and ±30ppm tolerance at the specified temperature range to ensure compatibility with existing oscillator circuits.
