Here are some problem that I'm confused when implement with AD9364.
Is there anything reference design and SDK need to modify or do if changing the part AD9361 to AD9364?
I already read the reference design before but I cannot change the IP util_dac_unpack and util_adc_pack into 1 channel. Therefore I redesign the interface below Maybe you can tell me , is there any error in my design show as <Figure>.
I had tried to generate three kinds of pattern to test look up table to test my interface connect to AD9364 correct or not .The test pattern had written in a look up table. When the stream FIFO accept data, address will be count up( shown as <Figure 2> ).
First pattern is single tone with 1MHz, performance of the waveform seems very smooth and similar to original waveform <Figure 3>.
In Second pattern , which is QPSK modulated signal with random data which pass through a Low Pass Filter and Interpolated by 4 .
Compare to first pattern , the waveform not smooth longer also cannot recognized.
It's seem there are some problems with AD9364 configuration, is there any SDK configuration example that can study. Also I hope that you can have some suggestions for me.
