AKD5353 Datasheet, PDF (2/17 Pages) Asahi Kasei Microsystems – EVALUATION BOARD REV.B FOR AK5353

ASAHI KASEI
[AKD5353]
n Analog Inputs
J1(AINL) and J2(AINR) are used.
The analog inputs are single-ended and each signal range is nominally 3.0Vpp@5V.
It is proportional to VA (Vin=0.6xVA).
n Operation sequence
1) Set up the power supply lines.
[VA] (red) = 2.7∼5.5V : for VA of AK5353
[3V] (orange) = 2.7∼5.5V : for VD of AK5353
[5V] (red) = 3.4∼5.5V : for logic
[AGND] (black)= 0V : for analog ground (including AGND and DGND of AK5353)
[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 and DIP switches. (See the followings.)
3) Power on.
The AK5353 should be reset once bringing SW4 (5353_PD) “L” upon power-up.
n Evaluation mode
1) DIT (Optical Link) <default>
PORT1 (TOTX174) is used. DIT generates audio bi-phase signal from received data and which is output
through optical connector (TOTX174). It is possible to connect AKM’s D/A converter evaluation boards on
the digital-amplifier which equips DIR input. JP6 and JP7 should be selected same mode as AK5353. In case
of using external clock through a BNC connector (J3), select BNC on JP5(CLK) and short JP4(XTE).

2) Using D/A converter board
The AK5353 can be evaluated by distortion analyzer using various AKM’s D/A converter evaluation boards.
They can be connected by 10pin flat cable via PORT2(DAC/ROM). If the AKD5353 feeds all interface signals
(MCLK,BICK,LRCK) to D/A converter board, jumper set up is same as 1) (See above). If all interface signals
are fed from D/A converter board, jumper set up is same as 3) (See below).
