I am using AD5764 evaluation kit & working with evaluation software as well as STM32F407 discovery board. I have sent data from STM32 to J21 connector of AD5764 eveluation kit & woking fine.
Now I have made a PCB with reference from evaluation kit data sheet. This PCB is working when I connect SYNC, SCLK & SDIN from test points that are between ADG774 mux and AD5764.
Basically I send data both to evaluation kit & PCB & both works fine.There is a problem when I send data to PCB directly from STM32F407 discovery board individually.
Please tell me how to solve this problem. Is it necessary to put mux to PCB as well?
Thanks in advance.
