MediaCard Multipurpose Eval board
Introduction
The MediaCard Multipurpose Eval Board, is being used to evaluate various components and techniques, which will be my
first attempts with these components, some of the new components that i will be using for the first time, are components
for interfacing DDR2, HDMI, SATA, CODEC and SD 4 Bit mode.
The above requires some more advanced techniques regarding signal integrity, transmission line impedance, differential,
and delay line matching for some of the high speed devices.
As statet above this project as such has no higher purpose, regarding as a finished "product" but rather for evaluating,
even throught I have worked with the most of the disciplines via my job, it shall be interesting working off hours
on these techniques, so that I can use this "new" knowlegde on my upcoming projects.
Features:
- CPU Board: EzRegaNUT LPC2214, EzRegaNUT AT91RM9200.
