AKD4358-SC
AK4358 Evaluation board Rev.0
GENERAL DESCRIPTION
The AKD4358-SC is an evaluation board for the AK4358. The AK4358 accepts up to192kHz PCM data
and 1-Bit DSD data making it ideal for a wide range of applications including DVD-Audio and SACD. The
AKD4358-SC has a digital audio interface that can interface with digital audio systems via opt-connector
or RCA connector. The AKD4358-SC also has several ports allowing you to interface the AK4358 to
external devices such as a DSP, DSD processor or AC3 decoder.
„ Ordering Guide
AKD4358-SC --- AK4358 Sound quality Evaluation board
(Cable for connecting the board with printer port of an IBM-AT compatible PC and
control software is packed with this. This control software does not operate on
Windows NT.)
FUNCTION
• On-board 2nd order LPF
• On-board clock generator (AK4113)
• Compatible with 3 types of interface
- Direct interface with AKM’s A/D converter evaluation boards
and direct interface
- On-board AK4113 (DIR) that accepts optical or BNC Input.
- Direct interface with DSD Decoder via 10pin header
• 10pin header for serial control interface
- Supports I2C and 3-wire control interface

Table 1. Set up of power supply lines
Each supply line should be distributed from the power supply unit.
2) Set-up jumper pins and DIP switches for desired mode. (See Evaluation Mode Setup.)
3) Power on.
The AK4358 should be reset once by bringing SW1(PDN) “L” upon power-up.
„ Evaluation Mode Setup
Only PCM Mode is supported.
1. DIR (COAX) (Default)
It is possible to evaluate the AK4385 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the
received data through BNC connector (J1). Setting of jumper is shown below.
COAX is recommended for an evaluation of the Sound quality.

„ Serial control
The AKD4358-SC can be controlled via the printer port (parallel port) of
an IBM-AT compatible PC. Connect PORT2(uP-I/F) to the PC with the
10-wire flat ribbon cable packed with the AKD4358-SC.
The pin layout of PORT2 is shown in Figure 4. Proper connection makes
the flat ribbon cable going away from the board.
