Table 1. Set up of power supply lines
Each supply line should be distributed from the power supply unit.
2) Set-up the jumper pins
3) Set-up the DIP switches. (See the followings.)
4) Power on
The AK4346 should be reset once bringing SW1 (PDN) “L” upon power-up.
„ Evaluation mode
1.
DIR(COAX) (default)
J1 is used for the evaluation using such as CD test disk. The DIR generates MCLK, BICK and LRCK SDATA from the received
data through BNC connector (J9). Setting of jumper is shown below.
COAX is recommended for an evaluation of the Sound quality.

„ External analog circuit
The 2nd order LPF (fc=111.8kHz, Q=0.714) which adds differential outputs of the AK4346 is implemented on the board.
When the further attenuation of the out-band noise is needed, some additional LPF is required. Analog signal is output
through BNC connectors on the board. And the output level of the AK4346 is 5.68Vpp@5V.
