Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix designation to confirm compliance with RoHS3 standards and environmental regulations. Confirm that the 16-TSSOP package dimensions align with the target PCB footprint constraints. Ensure that the operating temperature range of -40°C to 85°C meets the thermal requirements of the intended deployment environment before finalizing procurement decisions.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed 3:1 input-to-output frequency ratio is required without the need for programmability. Verify that the 1.1GHz maximum frequency capability satisfies the system's spectral requirements. Ensure the power supply voltage remains within the specified 2.7V to 5.5V range to maintain proper operation of the internal PLL circuitry.
