How properly i could configure high speed AD9748(DAC) to STM32F429? As i can see that STM32 has pins PA4 and PA5 that could be used as DAC_OUT. I have been trying to look for this interface and I am not able to proceed forward.

PA4 and PA5 are outputs of the DAC built into STM32.

Looking at the AD9784 datasheet, it's a parallel-data driven DAC, so you connect its DBx signals to a port on STM32, set the desired 8-bit value on that port, and then connect its clock to another port pin and toggle that pin.
