LC89091JA
8.6.4 Serial audio data input format (SDIN)
 _{The LC89091JA is provided with a serial data input pin of SDIN.}
 _{The format of the serial audio data input to SDIN and the demodulation data output format must be identical.}
 _{The SDIN data to be input must be synchronization with the BCKO and LRCKO clocks.}
 _{The data input from the SDIN pin is through-output to the DATAO pin. Data format conversion cannot be performed.}
 _{Normally, SDIN input data is output to DATAO pin when PLL is unlocked. But, with the ADMODE register setting,}
the SDIN input data is output to DATAO regardless of the locked/unlocked status of the PLL.
 _{The SDIN pin must be connected to GND when it is not used.}
