„ Evaluation modes
In case of the AK4556 evaluation using the AK4114, it is necessary to correspond to the audio interface format.
RX and TX use BNC connector at evaluation of Quad Speed with the AK4114.
Applicable evaluation modes
(1) Evaluation of Loopback mode using the AK4114 <default>
(2) Evaluation of DAC using DIR of the AK4114
(3) Evaluation of ADC using DIT of the AK4114
(4) All interface signals including master clock are fed externally.
(1) Evaluation of Loopback mode using the AK4114
X’tal oscillator (X1) 24.576MHz is used.
(1-1) Slave mode <Default>
