I have a 500 MHz Logic Analyzer, that has the option to display analog data also. I created a test board using an AD9059 to convert from analog to digital at 60MSPS and everything works well. AD9059 is a double ADC, so I can measure 2 analog inputs at the same time.
But there are a few improvements/additions that I want to add, but it's a hell finding parts that are fast enough.
First of all I want an 8 bit optocoupler that can go up to 60MHz (it would be even better if it would go up to 500MHz)
Why do I want that ? because I want to separate the ground of the ADC converter with the logic analyzer, this way I am not limited to what I want to measure.
Second, I need some kind of logical switch to select what analog I want to use, and when I don't use the analog, to "pass through" all the 8 bits (ports). I think this can be accomplished with 2 AND gates, and one OR gate. And I need the "switch" (logical gates) to work at 500 MHz, since the logic analyzer works at that speed.
I attached a picture with the logical switch that I want to use.
I also attached a diagram with what I want to accomplish. Each line is actually 8 bits (8 ports).
