Multiple High Speed ADCs via serial LVDS

Hi everybody, for a new system there is the need to digitize data with 12 Bit/80Msps from up to 20 channels. To date the idea would be using multiple Quad ADCs with serial LVDS links source ...

Nobody to comment on this?

Too sad :-(

I don't recall seeing this post.

One thing your analysis/description has missed is what needs to happen to the data once you receive it.

Sure you could get all of the data onto one FPGA, but if that data needs to "go somewhere", then you need enough bandwidth to get it off the device too.

What about signal processing? What needs to be done?

Why have you selected 12-bits at 80MHz? What is the bandwidth you are interested in, and what is the dynamic range of the input signals?

Cheers,

Dave
