regarding modifying fmcomms1 reference design with zedboard

 

 

 

hi,

     i am using fmcomms1 board along with zedboard and running the setup on no os driver , i have built the reference design and run the sinewave example and everything seems to be working well. now i have a custom ip which generates i and q data (16 bits each ) which i want to drive inside the ad9122 ip ,but my problem is i do not understand how i can drive my 16 bit i and q data inside the ip as there are two inputs on ad9122 dac_data0 and dac_data1 , can anyone help me undestand how the data is passed into these input pins and also how it is recieved on the adc side , how i can get back the same i q data on reciever in 16 bit format. thanks

regards

rahul
