AK4112B Evaluation Board Rev.A
GENERAL DESCRIPTION AKD4112B is the evaluation board for AK4112B, 96kHz digital audio transceiver. This has optical and BNC connector to interface with other digital audio equipment. The AKD4112B is also available to output analog data via on-board DAC, AK4394. n Ordering guide
AKD4112B --Evaluation board for AK4112B (A cable for connecting with printer port of IBM-AT compatible PC and a control software are packed with this.)
FUNCTION o Digital interface -S/PDIF : 4 channel input ( optical or BNC) 1 channel output ( optical or BNC) - Serial audio data I/F : 1 output ( for DIR data output. 10-pin port) o Analog interface -DAC output : Differential stereo output (Lch/Rch) o 10pin header for serial control interface

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.
