Important: In Gen 1 and Gen 2, there are only 20 mA (2.5V) and 32 mA (3.0V) modes available. A backwards compatibility mode is provided in Gen 3/DFE IP to accommodate existing hardware design. When configuring in this mode, the VOP feature is no longer available, the RF-DAC works as in Gen 1 and Gen 2, outputting 20 mA with a 2.5V power supply and 32 mA with a 3.0V power supply on DAC_AVTT.
Note: The power supply scheme is shared by all tiles on chip, so either VOP mode or 20/32 mA mode is available for one chip. Enabling VOP on one tile and 20/32 mA mode on others is not allowed.
