I wonder what communication method (i2c, UART, SPI) does AD9235 use and which pin is for communication. And if I want to achieve full 20MSPS, what is the minimum frequency of CLK source. Is Arduino Uno R3 powerful/fast enough to communicate with AD9235? I also have TI F28379D and TI TM4C123GXL board. Can any of my microcontroller board communicate with AD9235?
