DOUT1
PCM signal output of channel 1 when the parallel mode is selected.
The PCM output signal is output from MSD in a sequential order, synchronizing with the rising
edge of the BCLK signal.
MSD may be output at the rising edge of the XSYNC signal, based on the timing between BCLK
and XSYNC.
This pin is in a high impedance state except during 8-bit PCM output. It is also in a high
impedance sate during power saving or power down mode.
When the serial mode is selected, this pin is for the output of serial multiplexed 2ch PCM signal.
A pull-up resistor must be connected to this pin because it is an open drain output.
This device is compatible with the ITU-T recommendation on coding law and output coding
format.
The MSM7534(A-law) outputs the character signal, inverting the even bits.
DOUT2
PCM signal outputs for channel 2 when the parallel mode is selected.
The PCM output signal is output from MSD in a sequential order, synchronizing with the rising
edge of the BCLK signal.
MSD may be output at the rising edge of the XSYNC signal, based on the timing between BCLK
and XSYNC.
This pin is in a high impedance state except during 8-bit PCM output. It is also in a high
impedance state during power saving or power down modes.
When the serial mode is selected, this pin is left open.
A pull-up resistor must be connected to this pin because it is an open drain output.
This device is compatible with the ITU-T recommendation on coding law and output coding
format.
The MSM7534(A-law) outputs the character signal, inverting the even bits.
