[Discuss-gnuradio] Analog Devices ADC

[Kimsey Pollard]

I have acquired an Analog Devices ADC 14bit 80msps chip mounted on a pcb 
reference board.

It is designed to be connected to the following fifo board for testing.

The connector on the fifo board is parallel, and Analog Devices can't tell me
how it is controlled.  The Demo software with the Fifo board is proprietary.
(It shows the basic signal and fft's etc. but can't stream continuously to 
a file)

However, with any luck I will figure out how to talk to the fifo board with 
something else.
The object would be to feed a data stream into something like Matlab Simulink
where filters and various transforms are blocks which can be modified and 
tweaked
easily.  I also have Labview (The new version 7 can output to FPGA's and 
Palms).
Since I'm more familiar with the software side, apologies in advance for 
asking dumb
physical board level questions.

Today's question:  If Ethernet boards are optimized transceivers which are also
operationally speaking mostly software, can it have any applicability in 
the HDTV
or SDR arena? That is, what is moving on ethernet is an analog wave form of 
digital signal
which represents an encoding type like tcpip, netbios, appletalk.  I 
realize the
devil is in the details but could the following be a possibility:  a 
gigabit (1000)
ethernet card which has either an antenna or wire input which can 'hear' an
HDTV encoded signal which is decoded in software?  I just seems to me that 
the ethernet
board is an SDR type example of a 'cheap', minimal hardware front-end and most
all the action is in software.
