Operation Sequence
(1) Set up the power supply lines.
[The jumper pins should be set as following]
JP4
TVDD
(Short)
JP6
VDD
(Short)
JP7
P-DVDD
(Short)
JP5
PIC-VDD-SEL
1.8V 3.3V
Set up the power supply lines.
Name Color Voltage Comment Attention
+3.3V Red +3.3V Regulator,
Input/Output buffer
Should always be connected.
GND Black 0V Ground Should always be connected.
Table 2. Set Up of Power Supply Lines
Each supply line should be distributed separately from the power supply unit. The regulator on the board that
converts 3.3V to 1.8V can also supply TVDD of the AK7736A.
(2) Set up the evaluation mode, jumper pins and connectors. (according to the following section)
(3) Connect the board to a PC with a USB cable via the AKD77XX-HF-CONTROL-BOX (called
“CONTROL-BOX” hereafter) which is included in this package. It is required to push down the reset button
(yellow) of the CONTROL-BOX to initialize the USB control chip.
(4) Power On
(5) Start the control software and set up registers by PC. (according to the following section)

Evaluation Mode
In case of evaluating theAK7736A by using the AK4118A, it is necessary that audio interface format of both
devices are matched. Refer to the datasheet for audio interface format of the AK7736A, and refer to
“Jumper Pin and Switch Setting” for audio interface format of the AK4118A.
Applicable Evaluation Mode
(1) Digital-to-Digital Evaluation using ADC-Port and DAC-Port: CKM Master Mode = 0/1
(2) Digital-to-Digital Evaluation using ADC-Port and DAC-Port:
CKM Slave Mode = 2/3/4/5
Refer to the “Control Software” section of this manual and the datasheet of the AK7736A for FPGA, the AK4118A
and control register setting of the AK7736A.
