Diy 4 X CS4328 dac

[JC951t]

Hi Guys,
Over the years I've built 2 dac kits base on
the Cs4328. Have always like it's sound event
till today. Right now I have on hand a couple
of spare dacs and would like to try my hand at
making a 4 X parallel CS 4328 dac to be driven
by the I2S connection from my CD Pro 2.
Pls kindly advice me on the best way to implement
the built.

1. Grounding. Should the grounding be splitted
between digital & analog ground on the PCB ?

2. Which type regulators are most suited for the
CS 4328 interms of sound quality. I've only
gone as far as adjustable LT regulators.

3. Should I use the internal clock or run an external
clock ?

4. Is it better to reclock all 3 data lines ? If so, how
best to implement this ?

5. I'm remember Sheldon Stokes had a CS4328 diy
design but I can no longer find it on the net.
It would be great if anyone can direct me to
a link.

As the CS4328 is an obsolete item, I hope someone
out there could guide to through this built.

Thanks you all

I'm not sure if this is what you were reffering to in point 4. But this came up with google as page: http://www.quadesl.com/dac.html

As for as point 3 concerced, keep the traces as short as possible and equal in length if longer. This is always good practice for higher frequency signals.
