■
The AK4392 has channel-independent zeros detect function. When the input data at each channel is continuously zeros
for 8192 LRCK cycles, the DZF pin of each channel goes to “H”. The DZF pin of each channel immediately return to “L”
if the input data of each channel is not zero after going to “H”. If the RSTN bit is “0”, the DZF pins of both channels go to
“H”. The DZF pins of both channels go to “L” at 4 ~ 5/fs after RSTN bit returns to “1”. If DZFM bit is set to “1”, the DZF
pins of both channels go to “H” only when the input data for both channels are continuously zeros for 8192 LRCK cycles.
The zero detect function can be disabled by setting the DZFE bit. In this case, DZF pins of both channels are always “L”.
The DZFB bit can invert the polarity of the DZF pin.
■
The AK4392 can select input/output for both output channels by setting the MONO bit and SELLR bit. This function is
available for any audio format.
