CMOS-compatible control pin for optimizing the configuration of the AD9460 analog front end. Connecting SFDR to AGND optimizes SFDR performance for applications with analog input frequencies <200 MHz for 80 MSPS and 105 MSPS speed grades. For applications with analog inputs >200 MHz, connect this pin to AVDD1 for optimum SFDR performance; power dissipation from AVDD2 increases by ~70 mW for the AD9460BSVZ-80 and ~20 mW for the AD9460BSVZ-105.
