    Part Number: AFE7225 Tool/software: Hello, I wanted to purchase the AFE7225EVM board. It appears that the SPI interface is mainly manipulated via a GUI. I wanted to write custom SPI commands in software to send to the chip. This would allow me to test…

    Part Number: AFE7225 The docs cover DFS_RX and DFS_TX which seem limited to LVDS-only (DFS_TX is in 5.7 - LVDX TX INPUT INTERFACE REGISTERS, and DFS_RX is in 5.8 - LVDS RX OUTPUT INTERFACE REGISTERS). Is there a CMOS equivalent? The documentation is…
