The AD73322 evaluation board features a selectable number of codecs in
cascade (from 1 to 4). It can be interfaced to an ADSP-2181 EZ-KIT Lite or to
a Texas Instruments EVM kit.
The upgrade consists of a connector that is used to connect the EZ-KIT to the
AD73322 evaluation board. This option is intended for owners of the EZ-KIT
Lite.
The EZ-KIT Lite has been modified to allow it to interface with the AD73322
evaluation board. This option is intended for users who do not already have an
EZ-KIT Lite.
