re: RADX, Xilinx and ADI demo advanced, programmable EdgeQAM solutions

NO RATINGS
I was talking to the folks from RADX Technologies, Xilinx, and Analog Devices about all of this a few days ago. Now, just about everything about this technology is incredible ... but having said that, one thing that REALLY caught my eye was the AD9129 Digital-to-Analog (DAC) from Analog Devices. I mean, come on ... with 5.6 GSPS (gigasamples per second) and its 1.4 GHz of bandwidth, this enables the full cable spectrum to be synthesized in a single RF port. This dual-port device consumes 1.1W, which is 1/3 the power of competitive devices (I could tell you how they do this, but then they would send someone round to kill me). It also consumes only ~1/2 the pins of competitive devices (I think we're talking ~50 pins compared to ~100). As I say, this is a dual-port device. Now, when you think that a typical EdgeQAM system might require 80 to 100 ports, this means that you can be saving hundreds of watts of power and thousands of traces on the board. I am not an analog man, but I have to say that even I am impressed!!!
