Graham, thanks for your thoughts, sorry for delayed reply.
I am hoping that the Arm chip can cope with the data ratre involved,
certainly it will be a challenge. The tdm audio out thing was only that I
do want HDMI video out, and didn't want its possible audio use to interfere
with tdm input.
The ADC can be set up to run audio format TDM. You have two MCASP, which
are high speed multi-channel TDM engines to play with.
(Although I think they only did a real good job of pinning out MCASP0, need
to investigate, but one might be enough.)
Each are relatively independent bi-directional.
Hi
William: Unfortunately the TI chips I found on the launchpads page have
multichannel interfaces, but not simultaneous: that is there is only one
actual ADC and multiple Sample/Hold units. In the application I'm
interested in, sampling truly simultaneously is one of the requirements.

I would suggest that you look at the MCASP peripheral feature on the
Beaglebone Sitara processor.
See "AM335x Technical Reference Manual", Chapter 22
There are two of them, and each is a multi-channel audio interface.
It looks like your AD7761 can be configured to run serial wire per
Perhaps you should be thinking of using an external dedicated processor for
your application ? Something that has decent on die ADCs. Something like
the TI C2000 line ?
There are many dev kits here which include but are not limited to just the
C2000 products:
Hi
I'm new to BB but not new to hardware/software engineering. My reason for
posting is that I am struggling to connect it to the Beaglebone in a way
that permits fast data capture, and I am hoping that someone might be able
to offer suggestions.
My (hobby) idea is to create a device that can
