■
The AK4614 has an overflow detect function for the analog input. The overflow detect function is enabled when the
OVFE bit is set to “1”. Overflow detection is applied to the analog input of each channel, and the result is OR’d. OVF1/2
pins goes to “H” according to the group set by OVFM2-0 bits, if analog input of Lch or Rch overflows (more than
-0.3dBFS). When the analog input is overflowed, the output signal of OVF1/2 pins have the same group delay as ADC
(GD = 16/fs = 333μs @fs=48kHz). OVF1/2 pins are “L” for 518/fs (=11.8ms @fs=48kHz) after PDN = “↑”, and then
overflow detection is enabled.
■
The AK4614 has two pins for zero detect flag outputs. Zero detect function is enabled when the OVFE bit is set to “0”.
Channel grouping can be selected by the DZFM3-0 bits.
and the DZF2 pin corresponds to the group 2 channels. DZF1 is AND operation of all twelve channels and DZF2 is
disabled (“L”) at mode 8. When the input data of all channels in the group 1(group 2) are continuously zeros for 8192
LRCK cycles, the DZF1 (DZF2) pin goes to “H”. The DZF1 (DZF2) pin immediately returns to “L” if input data of any
channels in the group 1(group 2) is not zero.
