We are using AD9253-125, and one channel failed to action. We meausred all what we can, but still no idea how to deal with it.
As the picture 400m_all_channels.jpg shows, channel 2 is low that others at the same DC voltage level. We have measured the voltage one the pins, all four channels are the same, but the results are different.
Besides, others sine waves showed, one data is wrong, but we meausre the pin using high speed oscilloscope and find no clue.
Could you provide any hints for this case ? Thanks so much!
