the problem I get is trying to understand which DACs do I need to select in order to use the results of such a DDS in the analog world. I will be using signals until around 100 MHz, so I will need a DAC capable of working at 200 MHz... I have no idea on how do I need to select the DAC. I see in datasheets that they detail a "setting time", which is typically in us margin... much too low.
I once tested a 100Mhz with VirtexIV-LX, from Analog devices in current mode, but the thing is that for higher frequencies there are only video decoders, you can use them for other purposes, yes..... but what's your application? Texas Instrument has very goode codecs.
