Evaluation board Rev.B for AK4367
GENERAL DESCRIPTION
AKD4367 is an evaluation board for 24bit DAC with built-in Headphone Amplifier, AK4367. The
AKD4367 has the interface with AKM’s ADC evaluation boards. Therefore, it’s easy to evaluate the
AK4367. The AKD4367 also has the digital audio interface and can achieve the interface with digital
audio systems via opt-connector.

(Cable for connecting with printer port of IBM-AT compatible PC and control
software are packed with this. This control software does not operate on Windows
NT.)
FUNCTION
• Compatible with 2 types of interface
- Direct interface with AKM’s A/D converter evaluation boards
- On-board AK4116 as DIR which accepts optical input
• 10pin header for serial control interface

n Operation sequence
1) Set up the power supply lines.
[+5V]
(red)
= 5V
[AGND]
(black)
= 0V : for analog ground
[DGND]
(black)
= 0V : for logic ground
Each supply line should be distributed from the power supply unit.
2) Set up the evaluation mode, jumper pins. (See the followings.)
3) Power on.
The AK4367 and AK4116 should be resets once bringing SW1 (DAC_PDN) and SW2 (DIR_PDN) “L” upon
power-up.
n Evaluation mode
Applicable Evaluation Mode
(1) In case of using DIR (Optical Link) <default>
(2) In case of connecting AK4367 with a external DSP
(1) In case of using DIR (Optical Link) <default>
PORT1 (DIR) is used. DIR generates MCLK, BICK, LRCK and SDATA from the received data through optical
connector (TORX141). Nothing should be connected to PORT3 (DSP).

Upper-side is “H” and lower-side is “L”.
[SW1] (DAC_PDN) : Resets the AK4367. Keep “H” during normal operation.
[SW2] (DIR_PDN) : Resets the AK4116. Keep “H” during normal operation.
n Indication for LED
[LED1] (ERF): Monitor INT0 pin of the AK4116. LED turns on when unlock or parity error occurs.
n Serial Control
The AK4367 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT2
(uP-I/F) with PC by 10 wire flat cable packed with the AKD4367.

3. [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 AK4367, click “OK” button. If not, click “Cancel” button.
n Indication of data
Input data is indicated on the register map. Red letter indicates “H” or “1” and blue one indicates “L” or “0”. Blank is the
part that is not defined in the datasheet.
n Attention on the operation
If you set up Function1 or Function2 dialog, input data to all boxes. Attention dialog is indicated if you input data or
address that is not specified in the datasheet or you click “OK” button before you input data. In that case set up the dialog
