This looks like an AM mis-configuration, possibly in the frame buffer driver/configuration.This could be many things still, but I don't think the THS is the issue.When you say "windowed mode is OK" do...

Hi Ed,I noticed that you cannot measure impedance of the DRL electrode according to the TI's PDF. I'm really disappointed with TI as a company and with their experts. I'm starting to believe that they...

Hi Aamir,Follow precisely the current path. If you have a 1k in series with 50k and current is 100uA you will have a problem as you will be outside the voltage compliance range for the IDAC. For the...

I looked at the waveform and found that the text data which I am seeing on the registers are closed captioning data in text mode. That is not the teletext signal. If I configure the Line mode registers...

That's a very good question. Unfortunately, I do not have a quick and easy way to model such a system.But it's something to experiment with. If you have a possibility to try different PCBs, I can give...

Hi,First, the sensitivity is relate to the distance between coil and metal, the smaller distance, the higher sensitivity. Second, you can use moving average filter to get a better sensitivity. Can you...

Hi,For this device your understanding of the clock rates is correct. You would supply a 500MHz clock to the ADC for a 500Msps sample rate and the DDR LVDS output clock would be 250MHz with a sample on...
