I am working on ADA4858-3 and I am facing some technical issue.
I designed Amplifier Driver using ADA4858-3 driving and equalizing a 100M VGA Cable ,based the application note written by an ADI application engineer via below link. Please check the attached schematic for my design.
I have serious smearing problem in the VGA output image even worse than the situation without this ADA4858-3 driver circuit.
Would you please help to check and give some professional advice?
