Hello, I am working on ADSP-2189 EZKIT Lite. My project is 'Real time implementation of baseband pi/4 DQPSK modem on dsp' . The problem I am facing is with AD73322 codec on the board. I have to take input from one channel and output inphase and quadrature signals to the separate channels. I am getting output from only one channel. I am sending I and Q samples alternatively. Can u please suggest how to use 2 channels on the 2189 EZ kit lite board. One more problem I am facing is though I am giving input to one channel I am getting two samples per sample period .. The data sheet says that if we give input to 2 channels then we will be getting 2 samples per sample period. Does the samething happen if we give input to one channel also?? someone plz help me to make the concept clear. Regards prafulla ---------------------------------
