Hi Prasad,
Purna Chandar with the local TI applications support have forwarded more information regarding your issue. I have send some suggestions regarding your applications and we can work offline so you do not have to post sensitive information on the forum.
One quick suggestion is that the error above looks like a two's complement/offset binary issue. You may change the config2 input data format setting to see if the waveform improves.
By the way, I could not see your video. Could you forward Purna the video or repost the video? Thanks.
