AKD4683-A
AK4683 Evaluation Board Rev.1
FEATURE
AKD4683-A is an evaluation board for AK4683, a single chip 24bit CODEC that has two channels of ADC
and four channels of DAC with internal DIR, DIT. This board has interfaces with AKM’s evaluation boards
for A/D converter and D/A converter and makes easy to evaluate AK4683. Also this board has the digital
audio interface and then achieves the interface with digital audio systems via opt-connector or RCA
connector.
„ Ordering guide
AKD4683-A --- AK4683 Evaluation Board
10 wire flat cable for connection with printer port of PC (IBM-AT compatible machine),
control software for AK4589, driver for control software on Windows 2000/XP are
packed with this.
Control software does not work on Windows NT
Windows 2000/XP needs an installation of driver.
Windows 95/98/ME does not need an installation of driver.
AK4683 supports the standard-mode I2C-bus (max: 100kHz), and does not support a
fast-mode I2C-bus system (max: 400kHz).
FUNCTION
† On-board clock generator (use AK4114, x2)
† Compatible with 2 types of digital audio interface
- Optical output/input and RCA input/output
- 10pin header for interface with external data source (x2)
† RCA connector for clock input with external clock source
† 10pin header for register control

2-1. 10-wire flat cable for register control
AK4683 can be controlled via printer port (parallel port) of IBM-AT compatible PC. Connect printer port
(parallel port) of PC and PORT2 (uP-I/F) of AKD4683-A by 10-wire flat cable (packed with AKD4683-A).
Take care of the direction of 10-pin connector and 10-pin header. (The red line side of 10-wire flat cable of
10-pin connector should be connected to No.5pin and No.6pin of 10-pin header.)
