Serial Audio Output Port Data Format (06h)
SOSF
0 - Serial audio output port is in Slave mode (default)
1 - Serial audio output port is in Master mode
OSCLK frequency (for Master mode)
0 - 64*Fso (default)
1 - 128*Fso
set as the source
00 - 24 bit resolution (default)
01 - 20 bit resolution
10 - 16 bit resolution
11 - Direct copy of the received NRZ data from the AES3 receiver (including C, U, and
V bits, the time slot normally occupied by the P bit is used to indicate the location
of the block start, SDOUT pin only, serial audio output port clock must be derived
from the AES3 receiver recovered clock)
0 - Left-Justified (default)
1 - Right-Justified (Master mode only)
0 - MSB of SDOUT data occurs in the first OSCLK period after the OLRCK edge
1 - MSB of SDOUT data occurs in the second OSCLK period after the OLRCK edge
0 - SDOUT transitions occur on falling edges of OSCLK (default)
1 - SDOUT transitions occur on rising edges of OSCLK
OLRCK clock polarity
0 - SDOUT data is for the left channel when OLRCK is high (default)
1 - SDOUT data is for the right channel when OLRCK is high
Master/Slave Mode Selector
Resolution of the output data on SDOUT and AES3 output when the sample rate converter is
Justification of SDOUT data relative to OLRCK
Delay of SDOUT data relative to OLRCK, for left-justified data formats
OSCLK clock polarity
