Presented at the 89th AES convention in Los Angles (Sept. 1990) was
"A Family of AES-EBU Interface Devices" by David J. Knapp from
Crystal Semiconductor Corp. of Austin, TX.

I would suggest you contact Crystal Semi. (phone number unknown).
The article implied that some devices were available and some were
on the drawing board.  I would appreciate hearing about anything learned.

I found out from Crystal Semi. that the AES/EBU transmitter is available
but the receiver will not be until June/July, which is the same as
Motorola.  I will be getting samples from both companies as soon as the
silicon is finished.   The receiver is what I really need since I want
to use a Pro-DAT recorder as an A/D front end to a NeXT computer.

	My senoir design project involves sigma-delta A/D conversion
of audio and then formating and transmission in AES/EBU format.

	I have obtained from Crystal Semiconductor an AES/EBU tranmitter
chip:  CS8402.  This Supports 7 different serial input formats including
Motorola DSPs.  It also can be set for either professional or consumer
formats and has line driver output.  The CS8401 does the same, but is 
programmable.  They were very nice to deal with, too!

Crystal Semiconductor: 1-(800)-888-5016

	The data sheets also conatain a summary of the AES/EBU format.
