Description
The CDB3318 evaluation board is an excellent means
for evaluating the CS3318 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 CS3318’s inputs and outputs may be inde-
pendently AC or DC-coupled to their respective I/O
connectors.
The Windows software provides a GUI to make config-
uration
communicates through the PC’s USB or Serial port to
configure the control port registers so that all features of
the CS3318 can be evaluated.
As an alternative to the serial control provided via a PC,
the evaluation board may be configured to accept exter-
nal control signals for operation in a user application
during system development.
To facilitate multi-CS3318 system design efforts, head-
ers are provided for connecting serial control signals
between multiple CDB3318 evaluation boards.

... The AD0, ENOut, and MUTE signals are re-driven versions of these signals as present directly on their respective I/O pins on the CS3318. This header may be used to connect the serial control signals be- tween 2 or more CDB3318’s (out of J89 on one and in to J17 on another) for multiple CS3318 I²C serial control evaluation. ...

... Step-by-step instructions for using the FlexGUI are provided as follows: 1. Download and install the FlexGUI software from www.cirrus.com/msasoftware. 2. Connect the CDB3318 to a host PC using the supplied USB cable or a 9-pin serial cable. 3. Apply positive power, negative power, and ground to the VA+, VA-, and GND binding posts respectively. ...

... The software is only capable of addressing the CS3318 at its default address. If the CS3318’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 CS3318 datasheet for more information about the device’s individual ad- dress. 6 Figure 2. Register Maps Tab CDB3318 DS693DB2 ...
