AKD4392-SB
AK4392 Sound quality evaluation board Rev.0
General Description
AKD4392-SB is an evaluation board for AK4392 corresponding to DVD-Audio, which is 32Bit DAC. The
AKD4392-SB includes a LPF which can add differential analog outputs from the AK4392 and also has a
digital interface. Therefore, it is easy to evaluate sound quality of the AK4392.

„ Evaluation mode
1.
DIR(COAX) (default)
The DIR generates MCLK, BICK and LRCK SDATA from the received data through BNC connector (J7). It is possible for
the evaluation using such as CD test disk.
Setting:R87 = open;
R88 = short (0Ω)
COAX is recommended for an evaluation of the Sound quality.
2.
DIR(Optical)
The DIR generates MCLK, BICK and LRCK SDATA from the received data through Optical connector (PORT2). It is
possible for the evaluation using such as CD test disk.
Setting:R87 = short (0Ω);
3.
R88 = open
All clocks are fed through the PORT1.
Setting:
-R54, R55, R56, R58 = open

External Analog Circuit
The differential output circuit and LPF is implemented on board. The differential outputs of AK4392 is buffered by non-inverted circuit(2nd
st
order LPF, fc=106.4k, Q=0.698, G=+3.9dB). LPF adds differential outputs(1 order LPF, fc=284k, G=-0.84dB). LME49710NA is used
for op-amp on this board that has low noise and high voltage torelance characteristics. Analog signal is output via BNC connectors on the
board. The output level is about 2.8Vrms ([email protected]=5.0V) by BNC.

Control Software Manual
„ Evaluation Board and Control Soft Settings
1.Set an evaluation board properly.
2.Connect the evaluation board to an IBM PC/AT compatible PC by a 10wire flat cable. Be aware of
the direction of the 10pin header. When running this control soft on the Windows 2000/XP, the
driver which is included in the CD must be installed. Refer to the “Driver Control Install Manual for
AKM Device Control Software” for installing the driver. When running this control soft on the
windows 95/98/ME, driver installing is not necessary. This control soft does not support the
Windows NT.
3.Proceed evaluation by following the process below.

„ Operation Overview
Function, register map and testing tool can be controlled by this control soft. These controls are selected by
upper tabs.
Buttons which are frequently used such as register initializing button “Write Default”, are located outside of
the switching tab window. Refer to the “■ Dialog Boxes” for details of each dialog box setting.
1. [Port Reset]: For when connecting to USB I/F board (AKDUSBIF-A)
Click this button after the control soft starts up when connecting USB I/F board
(AKDUSBIF-A).
2. [Write Default]: Register Initializing
When the device is reset by a hardware reset, use this button to initialize the registers.
3. [All Write]: Executing write commands for all registers displayed.
4. [Save]: Saving current register settings to a file.
5. [Load]: Executing data write from a saved file.
6. [Data R/W]: “Data R/W” dialog box is popped up.

1.[REG]: Register Map
This tab is for a register writing and reading.
Each bit on the register map is a push-button switch.
Button Down indicates “H” or “1” and the bit name is in red (when read only it is in deep red).
Button Up indicates “L” or “0” and the bit name is in blue (when read only it is in gray)
Grayout registers are Read Only registers. They can not be controlled.
The registers which is not defined in the datasheet are indicated as “---”.
