AKD4382
Evaluation board Rev.A for AK4382
GENERAL DESCRIPTION
The AKD4382 is an evaluation board for the AK4382, the 24bit, 192kHz D/A converter for DVD and AC3 amp. The AKD4382 has the interface with AKM’s wave generator using ROM data and with AKM’s A/D
converter evaluation boards. Therefore, it is easy to evaluate the AK4382. The AKD4382 also has the
digital audio interface and can achieve the interface with digital audio systems via opt-connector or BNC
connector.

Evaluation board for AK4382
(Cable for connecting with printer port of IBM-AT compatible PC
and control software are packed with this.)
FUNCTION
• On-board 2nd order LPF
• Compatible with 2 types of interface
- Direct interface with AKM’s A/D converter evaluation boards
and direct interface with AKM’s signal generator(AKD43XX) by 10pin header
- On-board AK4112A as DIR which accepts optical or BNC input
• 10pin header for serial control interface

n External analog circuit
The 2nd order LPF (fc=93.2kHz, Q=0.712) which adds differential outputs of the AK4382 is implemented on the board.
When the further attenuation of the out-band noise is needed, some additional LPF is required. Analog signal is output
through BNC connectors on the board. And the output level of the AK4382 is 5.5Vpp@5V.

n Operation sequence
1) Set up the power supply lines.
[+15V]
(orange)
= +12 ∼ +15V
[-15V]
(blue)
= -12 ∼ -15V
[4382_VDD] (red)
= 4.75 ∼ 5.25V (Note 2)
[AGND]
(black)
= 0V
[DGND]
(black)
= 0V
Note:
1. Each supply line should be distributed from the power supply unit.
2. JP3(REG) should be shorted and “4382_VDD” jack should be open if VDD of the AK4382 is supplied
from the regulator.
2) Set-up the evaluation modes, jumper pins and DIP switches (See the followings.)
3) Power on.
The AK4382 should be reset once bringing SW1(PDN) “L” upon power-up.
n Evaluation mode
Applicable evaluation modes
1) DIR (Optical Link or BNC) (default)
2) Using ROM data (AK43XX)
3) Using AKM’s evaluation board for ADC
4) Feeding all signals from external
1) DIR (Optical Link or BNC) <default>
The AK4112A(DIR) generates MCLK, BICK, LRCK and SDATA from the received data through
PORT1(TORX176: optical link) or J1(BNC). Used for the evaluation using CD test disk. Nothing should be
connected to PORT2(EXT). In case of using optical connector (TORX176), JP1(TORX/BNC) should be selected
to “TORX”. In case of using BNC connector, select “BNC”.

JP5

JP6

JP7

2) Ideal sine wave generated by ROM data
Connect the AKD43XX with PORT2(EXT). The AKD4382 sends MCLK to the AKD43XX which the
AK4112A(DIR) generates from the received data through PORT1(TORX176: optical link) or J1(BNC). And the
AKD4382 receives LRCK, BICK and SDATA from the AKD43XX.

3) Using AKM’s evaluation board for ADC
To evaluate the AK4382 with analog input, the AKM’s evaluation board for ADC can be used. MCLK, BICK and
LRCK and A/D converted data are sent to the AKD4382 through PORT2(EXT) via 10 pin flat cable.
