 I already have that one and it does appear that it
might hold the key. It in fact will be my first choice for
study should I be forced to do this sample rate conversion
the hard way )`:

 It's going to have to wait however being that I'm
going to have to ditch the DSP projects for some
unfinished analog projects for awhile.

 I was just hoping that before I do that, that I could just
do one more thing DSPwise which would be to hear what
my programs and analog modifications to the DSP
board would sound like at 96 KHz.

 But unfortunately, if someone can't point me to
some info that would enable me to do the conversion
in the aproximately one day that I have to spare right now,
then unfortunately determining it out from the datasheets
will probably take too long. Therefore, the 96KHz
experiment will just have to wait until I finish
 my analog projects  )`:

 Damn, I wish patience were one of my virtues :-)

 Thanks for the help.

 Hello,

Two things I want to do with my EZ Kit.
Firstly I want to goose the sampling frequency
up to 96KHz.

 Secondly I would like to use the EZ Kit as a USB
soundcard.

Regarding goosing the sample frequency;
I thought this was going to be easy since there's
a sampling frequency setting jumper on the board.
Doh!, That is, until I discovered that it's only for the
auxilliary DAC.

  Since the user manual and ADI
website seem to be woefully deficient of info regarding
how to get the codec to run at this higher sample rate,
my question is;
does anyone know of some resources that might
be helpful in my quest?

 I suppose I could figger it out from the datasheets of
the codec and processor, but it looks like a rather time
consuming proposition. Therefore, I'm hoping that someone
has already been through the drill and might be willing
to share the info (or links to such info)




 The second thing is concerning the EZ Kit being used
as a USB soundcard. I've pretty much re-designed the
analog portion of my EZ Kit and managed to improve it's
performance to such an extent that I'd really love to use
it as a soundcard to record some demo's of some of
my analog amplifier designs. So I guess the question
here is whether or not anyone has done this and just
like my first question, are there any resources available
regarding doing something like this ?

 I guess I could use the SPDIF port, but I am still curious
about using the USB since it would be a good educational
challenge.

 Thanks,
Dave Moore
