GENERAL DESCRIPTION
AKD5356 is an evaluation board for the portable digital audio 20bit A/D converter with Pre-Amp and
Analog Volume. The AKD5356 includes the analog input circuits (LINE and Pre-Amp) and also has a
digital interfacetransmitter. Further, the AKD5356 can evaluate direct interface with AKM’s D/A converter
evaluation board.
nOrdering Guide
AKD5356 ---Compatible with 2 types of interface
(Cable for connecting with printer port of IBM-AT, compatible PC and control software
are packed with this. This control software does not support Windows NT/2000/XP.)

EVALUATION BOARD MANUAL
n Operation sequence
1) Set Up the power supply lines
[AVDD] (Orange) = 2.0 ∼3.3V (typ. 2.5V, AVDD pin)
[DVDD] (Orange) = 1.8 ∼AVDD (typ. 2.5V, DVDD pin, U2:74LCV541, U5:74LCV07A)
[MVDD] (Green) = 2.4 ∼3.3V (typ. 2.7V, MVDD pin)
[VCC] (Red) = 5.0V (for digital logic except the AK5356)
[AVSS] (Black) = 0V
[DVSS] (Black) = 0V
[MVSS] (Black) = 0V
Each supply line should be distributed from the power supply unit.
DVDD and AVDD must be the same voltage level.
When the regulator (3V output) is used, “AVDD”terminal supplies “5V”.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the following)
3) Power on
The AK5356 and AK4103 should be reset once bringing SW1 = SW3 = “L”upon power-up.

(1) Evaluation of A/D using DIT (Optical Link) <Default Setting)
PORT1 (DIT) is used. On board DIT (AK4103) converts A/D data to an audio biphase signal, which is output
through optical connector (TOTX176). It is possible to connect AKM’s D/A converter evaluation boards or the
digital-amplifier that equips DIR input etc. Nothing should be connected to PORT3. When using an external
clock through a BNC connector, select “EXT”on JP11 (CLK) and short JP14 (XTE).

(3) Evaluation of A/D using DIT at MCLK=384fs.
PORT1 (DIT) is used. On board DIT (AK4103) is set to the master mode. The AK4103 provides BICK and
LRCK to the AK5356 from an external master clock (MCLK). When using an external clock through a BNC
connector (J8), select “EXT”on JP11 (CLK) and short JP10 (XTE). (Refer to Table 2, Table 3and Table 4for
the set up of the DIP switches. The master mode should be selected in Table 2. The master clock (384fs) should
be selected in Table 4.)
