Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range compliance when sourcing. Confirm that the 8-SOIC package matches your PCB footprint requirements. Ensure the design supports the 3.3 V supply rail and validates the 166 MHz maximum output frequency against system constraints before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple synchronized clock domains are required from a single source. The integrated triple-PLL architecture reduces board space compared to discrete solutions. Consider the flash configuration feature if rapid prototyping or field reconfiguration is necessary. Validate that the input frequency range aligns with available reference oscillators.
