... Inputs USB/RS232 PC Interface http://www.cirrus.com Description The CDB3308 evaluation board is an excellent means for evaluating the CS3308 analog volume control. Eval- uation requires an analog signal source and analyzer, power supplies, and a Windows PC compatible computer. Standard RCA phono jacks are provided to easily inter- face external analog signals with the evaluation board. Each of the CS3308’ ...

... The AD0, ENOut, and MUTE signals are re-driven versions of these signals as present directly on their respective I/O pins on the CS3308. This header may be used to connect the serial control signals be- tween 2 or more CDB3308’s (out of J89 on one and in to J17 on another) for multiple CS3308 I²C serial control evaluation. ...

... The software is only capable of addressing the CS3308 at its default address. If the CS3308’s individual address is changed, the software will loose communication with the device until it is reset, thereby returning to its default address. See the CS3308 datasheet for more information about the device’s individual ad- dress. 6 Figure 2. Register Maps Tab CDB3308 DS702DB2 ...
