SERIAL AUDIO DATA INPUT FORMAT (SDIN)

The SDIN pin is a serial digital audio data input that can accept 24bit data data from sources such as

an A/D converter output.

When the data input to the SDIN is output from the SDATO, a clock signal synchronized with the

SDIN input data must be output from the BCLK and LRCLK to produce useable signals. Except for

the Special Mode setting, the SDIN input must have the same format as the required output data

format.
