General Description
AKD4430-SB is an evaluation board for AK4430 (192kHz sampling 24Bit StereoΔΣDAC with 2Vrms
Output). AKD4430-SB has a digital audio interface (AK4115) of Optical input and can easily achieve the
interface withdigitalaudio system.Therefore, itis easyto evaluate the sound qualityof AK4430.

Comment
(1) LOUT, ROUT (BNC-JACK)
It isanalog signal output Jack. The signal is output fromLOUT/ROUT pins.
(2) COAX, PORT1, PORT2 (Digital signal connector)
COAX (BNC-JACK): Digital signal (SPDIF, Fs: 24～48kHz) is input to the AK4115. (Default)
PORT1 (Optical Connecter): Optical digital signal (SPDIF, Fs: 32～48kHz) is input to the AK4115.
PORT2 (10 pin header): The clock and data can be input and output with this connector.
(3) REG, VDD, AGND, CVDD, VCC
These are the power supply connectors. Connect power supply with these pins.
As for the detail comments, refer to the setup of power supply in P3.
(4) SW1, SW2 (Switch)
SW1: Setting of frequency of MCKO that is output from AK4115.
SW2: Reset of AK4115. Keep “H” during normal operation.

Table 1.Set up of power supply lines
Note 1 ) In case of using +3.3V power supply to connect VCC1, It is possible to supply the voltage to AK4115 and
the Logic circuit without using Regulator.
In this case, change to R36: Open Short (0Ω); R34,R35: Short (0Ω) Open
Note 2 ) In case of using +12V power supply to connect REG, Use regulator: T1 can supply AK4430 with clean
voltage. (Default)
In this case, change to R25,R44: Short (0Ω) Open; R37,R43:Open Short (0Ω); VDD, CVDD should
be open.
2) DIP Switch setting:
Refer to Table 2 and Table 3
3) Power Down:
The AK4115 should be reset once by bringing SW2 (AK4115 PDN) “L” upon power-up.
Evaluation mode
1. Using DIR(Optical Link)
The DIR generates MCLK, BICK, LRCK and SDATA from the received data through optical connector (PORT1:
TORX141).It is possible to evaluate the AK4430 byusingCD disk.
Setting: R19: Open 470Ω; R33:short (0Ω)Open
2. Using DIR(COAX) (Default)
The DIR generates MCLK, BICK, LRCK and SDATA from the received data through BNC connector (J3). It is
possible to evaluate the AK4430 by using CD disk.
Setting: R19: Open; R33: short (0Ω); (Default)
＊ COAX is recommended for an evaluationofthe Sound quality.
3. Supply all interface signals that includ master clock via PORT2 from external equipments..
Setting: R11: 5.1ΩOpen
R12, R13, R14: 51Open
R15, R16, R17, R18: Open51 or short (0)
Note) The above work of removing (open) or shorting resistors need to modify the connection by soldering.
