AK4631-VN Evaluation board Rev.1
GENERAL DESCRIPTION
AKD4631-VN is an evaluation board for the AK4631VN, 16bit mono CODEC with MIC/SPK amplifier. The
AKD4631-VN can evaluate A/D converter and D/A converter separately in addition to loopback mode
(A/D → D/A). AKD4631-VN also has the digital audio interface and can achieve the interface with digital
audio systems via opt-connector.

2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.)
3) Power on.
The AK4631VN and AK4114 should be reset once bringing SW1, 2 “L” upon power-up.
Evaluation mode
In case of AK4631VN evaluation using AK4114, it is necessary to correspond to audio interface format for
AK4631VN and AK4114. About AK4631VN’s audio interface format, refer to datasheet of AK4631VN.
About AK4114’s audio interface format, refer to Table 2 in this manual.
Applicable Evaluation Mode
(1) Evaluation of loop-back mode (A/D → D/A) : PLL, Master Mode (Default)
(2) Evaluation of loop-back mode (A/D → D/A) : PLL, Slave Mode (PLL Reference CLOCK: MCKI
pin)
(3) Evaluation of loop-back mode (A/D → D/A) : PLL, Slave Mode (PLL Reference CLOCK: BICK or
FCK pin)
(4) Evaluation of using DIR of AK4114 (opt-connector) : EXT, Slave Mode

a) Set up jumper pins of MCKI clock
“MCKPD bit” in the AK4631-VN should be set to “0”.
X’tal of 11.2896MHz, 12MHz, 12.288MHz, 13MHz, 24MHz or 27MHz can be set in X2. X’tal of 11.2896MHz
(Default) is set on the AKD4631-VN. Set “No.8 of SW3” to “H”.
When an external clock (11.2896MHz, 12MHz, 12.288MHz, 13MHz, 24MHz or 27MHz) through a RCA
connector (J8: EXT/BICK) is supplied, select EXT on JP21 (MCLK_SEL) and short JP17 (XTE). JP23 (EXT1)
and R26 should be properly selected in order to much the output impedance of the clock generator.

a) Set up jumper pins of MCKI clock
“MCKPD bit” in the AK4631VN should be set to “0”.
X’tal of 11.2896MHz (Default) is set on the AKD4631-VN. In this case, the AK4631VN corresponds to PLL
reference clock of 12.2896MHz. In this evaluation mode, the output clock from MCKO-pin of the AK4631VN
is supplied to a divider (U3: 74VHC4040), BICK and FCK clocks are generated by the divider. Then “MCKO
bit” in the AK4631VN should be set to “1”. When an external clock through a RCA connector (J8: EXT/BICK)
is supplied, select EXT on JP21 (MCLK_SEL) and short JP17 (XTE). JP23 (EXT1) and R26 should be properly

Explanation of each dialog
1. [Write Dialog]: Dialog to write data by mouse operation
There are dialogs corresponding to each register.
Click the [Write] button corresponding to each register to set up the dialog. If you check the check box, data
becomes “H” or “1”. If not, “L” or “0”.
If you want to write the input data to AK4631VN, click [OK] button. If not, click [Cancel] button.
2. [Function1 Dialog] : Dialog to write data by keyboard operation
Address Box: Input registers address in 2 figures of hexadecimal.
Data Box:
Input registers data in 2 figures of hexadecimal.
If you want to write the input data to AK4631VN, click [OK] button. If not, click [Cancel] button.
3. [Function2 Dialog] : Dialog to evaluate IVOL and DVOL
Address Box:
Start Data Box:
End Data Box:
Interval Box:
Step Box:
Input registers address in 2 figures of hexadecimal.
Input starts data in 2 figures of hexadecimal.
Input end data in 2 figures of hexadecimal.
Data is written to AK4631VN by this interval.
Data changes by this step.
Mode Select Box:
If you check this check box, data reaches end data, and returns to start data.
[Example] Start Data = 00, End Data = 09
Data flow: 00 01 02 03 04 05 06 07 08 09 09 08 07 06 05 04 03 02 01 00
If you do not check this check box, data reaches end data, but does not return to start data.
[Example] Start Data = 00, End Data = 09
Data flow: 00 01 02 03 04 05 06 07 08 09
If you want to write the input data to AK4642, click [OK] button. If not, click [Cancel] button.
