AK4342 Evaluation board Rev.2
GENERAL DESCRIPTION AKD4342-B is an evaluation board for 24bit DAC with built-in 2Vrms lineout, headphone, and Aux lineout amplifiers, AK4342. The AKD4342-B has the interface with AKM's ADC evaluation boards. Therefore, it's easy to evaluate the AK4342. The AKD4342-B also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide
AKD4342-B --Evaluation board for AK4342 (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.)
FUNCTION * Compatible with 2 types of interface - Direct interface with AKM's A/D converter evaluation boards - On-board AK4113 as DIR which accepts optical input * 10pin header for serial control interface

Evaluation Board Manual Operation sequence
1) Set up the power supply lines. [VCC] (red) = 5V [AGND] (black) = 0V [DGND] (black) = 0V Each supply line should be distributed from the power supply unit. The power is supplied from VCC jack to the AK4342 via the regulator. 2) Set up the evaluation mode, jumper pins. (See the followings.) 3) Power on. The AK4342 and AK4113 should be resets once bringing SW1 "L" upon power-up.
Evaluation mode
Applicable Evaluation Mode (1) In case of using DIR (Optical Link) It is possible to use the initial setting of the audio interface format (24bit MSB justified) to evaluate the AK4342. (2) In case of connecting AK4342 with a external DSP
(1) In case of using DIR (Optical Link) PORT1 is used. DIR generates MCLK, BICK, LRCK and SDATA from the received data through optical connector (TORX141). Nothing should be connected to PORT2 (DSP).

Other jumper pins set up
JP3 (GND): Analog ground and Digital ground. OPEN : Separated. SHORT : Common. (The connector "DGND" can be open.)
The function of the toggle SW
Upper-side is "H" and lower-side is "L". [SW1] (DAC/DIR_PDN) : Resets the AK4342 and AK4113. Keep "H" during normal operation.
Indication for LED
[LED1] (INT0) : Monitor INT0 pin of the AK4113.
