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

EVALUATION BOARD MANUAL

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.)
