AKD5388-A
AK5388 Evaluation Board Rev.4
GENERAL DESCRIPTION
AKD5388 is an evaluation board for the digital audio 24bit 216kHz 4ch A/D converter, AK5388. The
AKD5388-A includes the input circuit and also has a digital interface transmitter. Further, the AKD5388-A
can achieve the interface with digital audio systems via opt-connector.
AKD5388-A is an evaluation board for AK5388, of 216kHz sampling 24bit 4ch A/D converter for
professional audio. AKD5388-A has analog input buffer circuits, clock generator circuits, and digital audio
interfaces. Therefore it can achieve the interface with digital audio systems via optical connector. And it
can achieve the direct interface with AKEMD’s D/A converter evaluation boards of via 10-line flat cable.

Setting
This connector should be connected.
And this connector is used when AVDD of AK5388 is
supplied from regulator T1 and DVDD of AK5388 is
supplied from regulator T2. In this case, JP9 and JP10
should be REG side. When this is REG side, +5V and
+3.3V connector should be open. (Default)
This connector should be connected.
This connector is used when AVDD of AK5388 is
supplied from +5V connector without regulator T1. In
this case, JP9 should be +5V side.
This connector is used when DVDD of AK5388 is
supplied from +3.3V connector without regulator T2.
In this case, JP10 should be +3.3V side.
This connector should be connected.
+15V
This connector should be connected.
This connector is used when DGND is supplied besides
AGND. In this case, JP15 should be open. (Default)

Table 1. Power supply lines
(Note) 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 AK5388 and AK4101A should be reset once bringing SW3 = “L” upon power-up.
Note: When AK5388 is TDM mode, the AK4101A does not support the TDM mode. Therefore, PORT1 and PORT2
cannot be used. Also, when the sampling frequency is used by 96kHz or more, PORT1 and PORT2 cannot be
used. Please use PORT3 (DSP1) and PORT4 (DSP2).
Evaluation mode
(1) Slave mode
(1-1) A/D evaluation using DIT function of AK4101A
PORT1 and PORT2 are used. DIT generates audio bi-phase signal from received data and which is output
through optical connector (TOTX197). It is possible to connect AKEMD’s D/A converter evaluation boards on
the digital-amplifier, which equips DIR input. Nothing should be connected to PORT3 (DSP1) and PORT4
(DSP2). In case of using external clock through a BNC connector (J9), select EXT on JP11 (MCLK) and short
JP16 (XTE) and JP17 (EXT).

Analog input buffer circuit
An analog input buffer circuit example (1st order HPF; fc=0.70Hz, 2nd order LPF; fc=304kHz,
gain=-14.5dB) is shown in Figure 2. The analog signal is able to input through XLR or RCA connectors.
(For RCA input, jumper should be short. For XLR input, jumper should be open.) The input level of this
circuit is +/-15.4Vpp (AK5388: +/-2.9Vpp Typ.). When using this circuit, analog characteristics at
fs=48kHz is DR=118dB, S/(N+D)=TBDdB.
