AKD5385A
Evaluation board Rev.A for AK5385A
GENERAL DESCRIPTION AKD5385A is an evaluation board for the digital audio 24bit 192kHz A/D converter, AK5385A. The AKD5385A includes the input circuit and also has a digital interface transmitter. Further, the AKD5385A can achieve the interface with digital audio systems via opt-connector. n Ordering guide

n Operation sequence
1) Set up the power supplies lines. [AVDD] (red) = 4.75 5.25V [DVDD] (red) = 3.0 5.25V [+15V] (green) = +15V [-15V] (blue) = -15V [VCC] (red) = 5V [AGND] (black) = 0V [DGND] (black) = 0V
: for AVDD of AK5385A (typ. 5.0V) : for DVDD of AK5385A (typ. 3.3V) : for Op-amp : for Op-amp : for logic : for analog ground : for logic ground
Each supply line should be distributed from the power supply unit. 2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.) 3) Power on. The AK5385A and AK4103 should be reset once bringing SW1 = "L" upon power-up.
n Evaluation mode
(1) Slave Mode (1-1) A/D evaluation using DIT function of AK4103 PORT1 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through optical connector (TOTX176). It is possible to connect AKM's D/A converter evaluation boards on the digital-amplifier which equips DIR input. Nothing should be connected to PORT2 (DSP). In case of using external clock through a BNC connector (J3), select EXT on JP8 (CLK) and short JP5 (XTE) and open JP10 (EXT).

(1-2) Feeding all clocks from PORT2 (DSP) Under the following set-up, all external clocks (MCLK, BICK, LRCK) can be fed through PORT2 (DSP). The A/D converted data is output from SDTO of PORT2 (DSP). Also, the A/D converted data is output through optical connector (TOTX176).

JP2 (AVDD) : Select AVDD for AK5385A AVDD : Supply from AVDD connector REG : Supply from regulator. AVDD connector should be supplied +15V. 3. JP6 (BCFS) : Select BICK frequency 256 : In case of MCLK=256fs/512fs 384 : In case of MCLK=128fs/384fs 4. JP7 (MCLK) : Supply MCLK frequency for 74HC4040 256 : In case of MCLK=128fs/256fs 512 : In case of MCLK=512fs 384/768 : In case of MCLK=384fs 5. JP9 (LRFS) : Select LRCK frequency 256 : In case of MCLK=256fs/512fs 384 : In case of MCLK=128fs/384fs
