How DAC in AD9361 works!?

Hi all,

 

I am using FMCOMMS2 with ZedBoard. I was wondering how the DAC works. We make a portion of data accessible to DAC through the DMA from a certain location in memory. Are these values treated as integers and then are transmitted or they are treated bitwise!? I mean since the DAC has a 12-bit resolution does it read the bits in memory with a step of 12 bits or how it works!?

 

Also there are two different DAC for two channels in AD9361. How do they get the data from the memory location using the DMA!?

 

Regards,

Jet
