The digital implementation in 16nm FinFET versus 65nm (typically used for analog RF components) results in more than 10Ã area reduction and 4Ã power reduction. Xilinx has innovated ideal design solutions to implement power integrity, digital calibration loops for high precision, and robust isolation strategies.

In high end RF systems, such as 5G radios, the requirements are so stringent that the source of this strongest unwanted tone can be the PLL. This article outlines how spurs in the input clock to the ADC or DAC may limit the SFDR. This in turn will set the requirements for the spurs for the input clock (from a PLL), in order to achieve a specific SFDR.
