Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliability during manufacturing.

Selection Notes

Select this component when a precise 10.779375 MHz clock source is required for 1.8V logic families. Consider the enable/disable feature if power conservation is critical for the application. Evaluate the physical size constraints to ensure the 2.0x1.6mm package fits within the available board space. Compare performance metrics such as phase noise and stability against other available options if high-precision timing is essential for the system operation.
