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

Evaluation Board Manual Operation sequence
1) Set up the power supply lines. [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. (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 (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).

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.

Serial Control
The AK4343 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT4 (CTRL) with PC by 10 wire flat cable packed with the AKD4343. When I2C bus mode is used, PORT4 should be directly connected to the I2C bus on the system. JP13,14 and 15 should be set to I2C bus mode to control the AK7830.
