Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct voltage, stability, and temperature grade alignment. Confirm that the ordering part number matches the required frequency tolerance and operational parameters before finalizing procurement orders to avoid integration errors.

Selection Notes

Select this component when a small form factor is critical alongside robust industrial temperature performance. Ensure the system design accommodates the 3.3V supply requirement and utilizes the enable feature if power optimization during idle states is necessary for the application.

Part Context

This oscillator belongs to the QTM252 series, which provides low-jitter solutions in a miniature footprint. The J suffix typically denotes specific manufacturing or packaging variations within the TXC/QST portfolio, ensuring compatibility with high-density PCB designs common in modern electronic devices.

Replacement Considerations

Direct substitutes may include other 2520 package CMOS oscillators from manufacturers like Epson or SiTime, provided they match the 30MHz frequency, 3.3V supply, and ±50ppm stability requirements while maintaining compatible pinout configurations.
