RF ENABLE
RF ENABLE Control Pin. CMOS-compatible control pin to optimize the configuration of
the AD9445 analog front end. Connecting RF ENABLE to AGND optimizes SFDR
performance for applications with analog input frequencies <210 MHz for 125 MSPS
speed grade and <230 MHz for the 105 MSPS speed grade. For applications with analog
inputs >225 MHz for the 125 MSPS speed grade and >230 MHz for the 105 MSPS speed
grade, this pin should be connected to AVDD1 for optimum SFDR performance. Power
dissipation from AVDD2 increases by 150 mW to 200 mW.
