Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 3.3V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0mm x 1.6mm package dimensions and thermal specifications. Check for RoHS compliance status if required by project regulations.

Selection Notes

Select this model when a precise 24.576 MHz clock signal is required for digital interfaces. The CMOS output simplifies integration without additional buffering. Consider the ±50 ppm stability sufficient for most standard UART, SPI, or I2C applications. The small form factor makes it suitable for space-constrained consumer electronics and industrial modules.

Part Context

This part belongs to the IQXO-540 series of standard crystal oscillators. It represents a solution for applications needing reliable timing without the complexity of programmable devices. The series offers various frequencies and packages to support diverse design requirements across automotive, industrial, and consumer sectors.

Replacement Considerations

Direct substitutes must match the 24.576 MHz frequency, 3.3V supply, CMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as rise/fall times and current consumption. Cross-reference with other manufacturers' equivalent parts ensuring identical mechanical and environmental ratings.
