... these clocks are not provided, the AK5353 may draw excess current and may not possibly operate properly because the device utilizes dynamic refreshed logic internally. If the external clocks are not present, the AK5353 should be in the power-down mode (PDN After exiting reset at power-up etc., the AK5353 is in the power-down mode until MCLK and LRCK are input. ...

... ASAHI KASEI n Power down The AK5353 is placed in the power-down mode by bringing PDN L and the digital filter is also reset at the same time. This reset should always be done after power-up. In the power-down mode, the VREF and VCOM are AGND level. An analog initialization cycle starts after exiting the power-down mode. Therefore, the output data SDTO becomes available after 4129 cycles of LRCK clock ...

... The ideal code is 000000H(@24bit) with no input signal. The DC offset is removed by the internal HPF. The AK5353 samples the analog inputs at 64fs. The digital filter rejects noise above the stop band except for multiples of 64fs. A simple RC filter (fc=150kHz) may be used to attenuate any noise around 64fs and most audio signals do not have significant energy at 64fs ...
