ASAHI KASEI [AKD4343-B] AKD4343-B AK4343 Evaluation board Rev.0 GENERAL DESCRIPTION The AKD4343-B is an evaluation board for the AK4343, Stereo DAC with built-in HP/RCV/SPK amplifier. The AKD4343-B has the interface with AKM’s ADC evaluation boards. Therefore, it’s easy to evaluate the AK4343. The AKD4343-B also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide AKD4343-B --- Evaluation board for AK4343 (Cable for connecting with printer port of IBM-AT compatible PC and control software are packed with this. This control software does not operate on Windows NT.)

[VCC] (red) = 5.0V (or 3.3V) [AGND] (black) = 0V [DGND] (black) = 0V Each supply line should be distributed from the power supply unit. When the power is supplied to the AK4343 via the regulator, JP21 should be set to “REG” side and VCC should be 5.0V.<default> (When the power is supplied from VCC jack to the AK4343 directly, JP21 should be set to “VCC” side and VCC should be 3.3V.) 2) Set up the evaluation mode, jumper pins. (See the followings.) 3) Power on. The AK4343 and AK4114 should be reset once bringing SW1 “L” upon power-up. And the AK7830 should be reset once bringing SW2(SPK_PDN) “L” upon power-up. Evaluation mode (1) Slave mode (1-1) Evaluation of Playback block (HP, SPK, LOUT) using DIR of AK4114 <Default> (1-2) All interface signals including master clock are fed externally. The AK4114’s audio interface format is fixed to LJ compatible. (1-1) Evaluation of Playback block using DIR of AK4114 PORT1 (DIR) is used. Nothing should be connected to PORT3 (DSP). JP6 BICK2 JP7 LRCK2 JP8 LRCK JP9 JP10 MCLK BICK JP11 SDTI DIR ADC The AK4114 operates at fs of 32kHz or more. If the fs is slower than 32kHz, any other evaluation mode without using DIR should be used. <KM083800> 2006/04 -2- ASAHI KASEI [AKD4343-B] (1-2) All interface signals including master clock are fed externally. PORT3 (DSP) is used. Nothing should be connected to PORT1 (DIR). JP6 BICK2 JP7 LRCK2 JP8 LRCK JP9 JP10 MCLK BICK JP11 SDTI DIR ADC (2) Master mode (2-1) Master clock is fed externally (2-1) Master clock is fed externally PORT3 (DSP) is used and MCLK is fed from PORT3.
