AKD4642-B
Evaluation board Rev.0 for AK4642
GENERAL DESCRIPTION
AKD4642-B is an evaluation board for the AK4642, 16bit CODEC with built-in MIC/HP/SPK amplifier. The
AKD4642 can evaluate A/D converter and D/A converter separately in addition to loop-back mode (A/D →
D/A). The AKD4642 also has the digital audio interface and can achieve the interface with digital audio
systems via opt-connector.

„ Operation sequence
1) Set up the power supply lines.

(red)
= 5.0V
[AGND] (black)
= 0V
[DGND] (black)
= 0V
: for logic
: for analog ground
: for logic ground
Each supply line should be distributed from the power supply unit.
3.3V is supplied to AK4642 and AK4114 via the regulator.
2) Set up the evaluation mode, jumper pins. (See the followings.)
3) Power on.
The AK4642 and AK4114 should be reset once bringing SW1 “L” upon power-up.
„ Evaluation mode
(1) Slave mode
(1-1) Evaluation of Recording block (MIC, ADC) using DIT of AK4114
(1-2) Evaluation of Playback block (HP, SPK, LOUT) using DIR of AK4114
(1-3) Evaluation of Loop-back using AK4114
(1-4) All interface signals including master clock are fed externally.
The AK4114’s audio interface format is fixed to I2S compatible.
(1-1) Evaluation of Loop-back using DIT of AK4114
PORT2 (DIT) and X1 (X’tal) are used. DIT generates audio bi-phase signal from received data and which is
output through optical connector (TOTX141). Nothing should be connected to PORT1 (DIR) and PORT3
(DSP).
