Evaluation mode
1) Evaluation of ADC
TOTX176 is used for digital output. Clock mode of the AK4112A should be set to PLL mode or X’tal mode.
2) Evaluation of DAC
TORX176 or BNC is used for digital input. Clock mode of the AK4112A should be set to PLL mode. “4112” should
be selected on JP4,5 and 6.
3) Loopback mode
Clock mode of the AK4112A should be set to PLL mode or X’tal mode. “4112” should be selected on JP4,5 and 6.
4) Evaluation of DAC using DSP
“DSP” should be selected on JP4,5 and 6.
