Arduino 50 MSPS DSO Oscilloscope with TDA8703

Last night I was testing a TDA8703 analog to digital converter and after trying 36 MHz I tried 50 MHz on a whim and it worked.  I also tried 60 MHz but the TDA8703 flaked off at that speed.

Here is a picture of the test setup.

This is what the LCD screen looks like.

Here is the video of it at 50 MSPS and 25MSPS.


Here is the schematic diagram.
