I seen few minutes before to post and I like them, I am more incline to document but sometimes I also watch some lesson. The Analog Device too is a good tutorial on how plane work and RF, take an Eye.
About DDR on daughter board I fear there where not enough pin, some need to be free for user interaction, a better solution, as I asked ,was just to use HDMI:
it can consume just 4 LVDS pair and one PLL, you can deserialise HDMI with a chip, fed VGADAC then analog monitor, if you do that on a short adapteur signal integrity can be better.
Anyway this has sense on old analog CRT monitor, if you own an LCD analog input is first converted to digital then fed serially to LCD panel on parallel or HDMI Like Lvds serial port.
