audio input extension for ADSP-21369 EZ-Kit Lite

Started by Arne Borsum September 13, 2006
Hi,

I am developing audio applications on the ADSP-21369 EZ-Kit Lite board.

The board has 8 channels audio output but only 2 channels input, 
although the DSP itself supports more channels.

Now I am searching for a extension board for the EZ-Kit which provides 6 
or more (analog) input channels. Is there anything like this availble?

Regards,

Arne Borsum

Cirrus makes an evaluation board for their CS42448 audio CODEC, which 
provides 6 ADC / 8 DAC channels. You should be able to jumper this board 
to a SPORT on the EZ-KIT.

Our dspstak 21369zx/zx2 boards are ADSP-21369 based. We have an I/O board, dspstak c192k48 that has 4 inputs and 8 outputs. You can stack up to 4 of these cards to create systems with up to 16 inputs and 32 outputs. We have special extender cards for balanced audio as well.
