- I even saw a couple of applications where digital FPGA pins (actually a LVDS receiver and a LVTTL output) were used to implement A/D conversion, through an external RC. Anyway this is a non conventional design and I don't think it leads to a straightforward implementation.

Hallo,

what you mean is a simple Sigma-Delta ADC like this http://www.altera.com/support/examples/dsp-builder/exm-sigma-delta-converter.html?gsa_pos=1&wt.oss_r=1&wt.oss=sigma .

There are several examples for those ADCs on web, but they are not easy to understand!
