Other Parts Discussed in Thread: TIDA-00069, ADS4249EVM, DAC3482
Hi Ti,
I have the problem about the DAC3482EVM output.
My project is using ADS4249EVM, TSW1400evm and DAC3482EVM.I give the 200kHz sine wave and 20MHz CLK to ADC4249EVM. And using HSDC Pro to download the firmware(TIDA-00069). and the DAC 3482EVM config file is.

And i can get the clear sinewave in the digital Oscillosocpe, but when I change the input sinewave to Squarewave or Rampwave, the output in the oscilloscope is not right.
can you tell me why?
