Input Setup
1. Digital audio data input
The digital audio data is a 16-bit serial signal in an MSB-first two’s complement format. The 16-bit serial data is
input from the DATA pin to an internal register on the rising edge of the BCLK signal, and is read in on the rising
and falling edges of the LRCK signal.
2. Mode setup
The method used to set the speed (normal/double), deemphasis, and digital attenuator settings differs depending on
the state of the mode pin (MODE).
When MODE is low: serial input mode
In this mode, the speed (normal/double), deemphasis, and digital attenuator settings are set by inputting serial data to
the DAT/MT pin.
<Data Format>
Notes:DAT/MT and SH/EMP: These pins must be held fixed (low or high) at all times other than the data transfer period (t1 in the figure).
LAT/ND: This pin must be held high at all times other than during data acquisition.
A0 (ND): Normal/double speed flag
A1 (EMP): Deemphasis flag
The deemphasis function supports operation at fs = 44.1 kHz.
No. 5537-6/11
