Evaluation board Rev.A for AK5355
GENERAL DESCRIPTION
AKD5355 is an evaluation board for the portable digital audio 16bit A/D converter, AK5355. The AKD5355
includes the input circuit and also has a digital interface transmitter. Further, the AKD5355 can evaluate
direct interface with AKM’s D/A converter evaluation board.

Evaluation board for AK5355
FUNCTION
• Compatible with 2 types of interface
- Direct interface with AKM’s D/A converter evaluation boards
- On-board AK4103 as DIT which transmits optical output
• BNC connector for an external clock input

: for digital logic except the AK5355
: for analog ground (including VSS of AK5355)
: for logic ground
Each supply line should be distributed from the power supply unit.
VD and VA must be the same voltage level.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.)
3) Power on.
The AK5355 and AK4103 should be reset once bringing SW1 = SW3 = “L” upon power-up.
„ Evaluation mode
Applicable Evaluation Mode
(1) Evaluation of A/D using DIT (Optical Link) <Default Setting>
(2) All interface signals including master clock are fed externally.
(3) Evaluation of A/D using DIT at MCLK = 384fs
(1) Evaluation of A/D using DIT (Optical Link)
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 PORT2. DIT (AK4103) operates at
SW3=“H”. When using an external clock through a BNC connector (J3), select “EXT” on JP4 (CLK) and short
JP3 (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 AK5355 from an external master clock (MCLK). When using an external clock through a BNC
connector (J3), select “EXT” on JP4 (CLK) and short JP3 (XTE). (Refer to a Table 1 ∼ 3 for the set up of the DIP
switch. The master mode should be selected in Table 2.)

injury or damage to person or property.
(b) A critical component is one whose failure to function or perform may reasonably be expected to
result, whether directly or indirectly, in the loss of the safety or effectiveness of the device or
system containing it, and which must therefore meet very high standards of performance and
reliability.
• It is the responsibility of the buyer or distributor of an AKM product who distributes, disposes of, or
