n Evaluation modes
(1) Evaluation for DIR (Digital output)
S/PDIF in(optical or BNC) – AK4112B – Serial Data out(10pin port)
(2) Evaluation for DIR(analog output via DAC)
S/PDIF in(optical or BNC) – AK4112B – DAC(AK4394) – Analog out(Balance XLR)
n Operating sequence
(1) Set up the power supply lines.
[-12V]
(Blue)
= -12 ~ -15V
[+12V]
(Orange)
= +12 ~ +15V
[Analog 5V] (Red)
= 5V
: Open when the JP15(REG5V) is short.
[AGND]
(Black)
= 0V
[Digital 5V] (Red)
= 5V
[DGND]
(Black)
= 0V
[Analog 3V] (Green)
= 3.3V
: Open when the JP13(REG3V) is short.
[AGND2]
(Black)
= 0V
[Digital 3V] (Green)
= 3.3V
Each supply line should be distributed from the power supply unit.
(2) Set up the evaluation mode and jumper pins. (See p.3.)
(3) Connect cables.
(4) Power on.
The AK4112B and AK4394 should be reset once bringing PDN(SW3) “L” upon power-up.
(5) Set up software.
Both the serial and parallel mode are available for AK4112B. AK4394 is fixed to
serial control mode. In the serial mode, The IBM-AT compatible PC can control
both AK4112B and AK4394 by using the printer port and PORT2 on the AKD4112B.
Connect PORT2 (uP-I/F) with PC by 10-line flat cable packed with the AKD4112B.
Take care of the direction of connector. There is a mark at pin#1.
The pin layout of PORT2 is as Figure 2.
