AD2433 with SOM carrier ez-kit
Evaluation boards
The AD243x standard power evaluation boards used in the demos are explained in the following subsections.
ADZS2433-MINI
Figure 39 shows a ADZS2433-MINI board which can be used as a standard power A2B master. The board has following peripherals
- AD2433 A2B transceiver
- 512K Self-Boot Memory (EEPROM)
Figure 39: ADZS-2433MINI
Hardware modifications
The following hardware modifications are required:-
- For all ADZS2433-MINI boards, remove R21, R18, R58, R59.
- For all ADZS2433-MINI boards, add R17.
- For the board with I2C address 0x68, remove R33 and add R34.
- For the board with I2C address 0x6A, remove R34 and add R33.
Jumper settings
The jumpers on the board must be in the following positions
EVAL-AD2433WB1BZ
Figure 40 shows EVAL-AD2433WB1BZ board which can be used as a standard power bus powered A2B sub node. The board has following peripherals
- AD2433 A2B transceiver
- Stereo Audio Codec (ADAU1961) with Line I/O
- 4 Microphones

Jumper settings
The following jumper settings are required:-
- P1 – 1-2
EV-21569-SOM Rev B
This is same as EV-21569-SOM
EV-SC594-SOM Rev B
This is same as EV-SC594-SOM).
EV-SOMCRR-EZKIT Rev A
This is same as EV-SOMCRR-EZKIT .
Connections
To run the sample demo, the following setup connections are to be made.
Figure 41: Multi-main connections using PC(Host) and ADSP-21596 SOM carrier kit and ADZS2433MINI’s
The step described in this section are recommended to run the following configurations
- AD2433 multi-main sample demo using ADSP-21596 platform and PC as host.
The Evaluation boards shall be connected in the following order.
- Connect the EV-21569-SOM to the EV-SOMCRR-EZKIT.
- Connect one of the two ADZS2433-MINI boards to J10 A2B interface of the EV-SOMCRR-EZKIT. Let this be “main node 0” with I2C address configured to be 0x68.
- Connect other ADZS2433-MINI to J11 A2B interface of the EV-SOMCRR-EZKIT. Let this be “main node 1” with I2C address configured to be 0x6A.
- For A2B chain 0:- ADZS2433-MINI (Main node 0) → EVAL-AD2433WB1BZ (Sub node 0) → EVAL-AD2433WB1BZ (Sub node 1), the connections are as follows
- Connect twisted-pair wire between the “B” connector on the main node 0 board and the “A” connector on the sub node 0 board.
- Connect twisted-pair wire between the “B” connector on the sub node 0 board and the “A” connector on the sub node 1 board.
- For A2B chain 1:- ADZS2433-MINI (Main node 1) → EVAL-AD2433WB1BZ (Sub node 2) → EVAL-AD2433WB1BZ (Sub node 3), the connections are as follows
- Connect twisted-pair wire between the “B” connector on the main node 1 board and the “A” connector on the sub node 2 board.
- Connect twisted-pair wire between the “B” connector on the sub node 2 board and the “A” connector on the sub node 3 board.
- Connect 12V power supply to the power connector of EV-SOMCRR-EZKIT.
