DDS-GEN—Part
2: The Generator
by
Robert Lacoste
Lucky
for us it was a cloudy night in France when Robert was
scheduled to write the second part of the article on
his DDS-GEN project! Don’t miss out as he covers
everything from hardware selection to software design
to prototype contruction this month.
Start
•
Direct Digital Synthesis?
• The AD9852 monster chip
• Hardware •
Prototype Construction
• On The Software Side
• Design Methodology
• What’s Next?
• Sources & PDF
The night I
sat down to write was supposed to be one of the best nights
of the year to see hundreds of meteors in the sky. I checked
the date in my diary months ago, but the sky here in France
stayed unfortunately cloudy. The good news is that it
was a marvelous opportunity to spend the evening on my
PC writing the second part of my DDS-GEN article!
Last month I
explained the DDS-GEN project—a high-performance,
0 to 120-MHz generator that uses direct digital synthesis
technology. We studied the user interface subsystem of
this project, the I2C-MMI, and now are ready to dig into
the DDS generator itself.
