LC890561W
12.5.2 Serial Audio Data Input Format (SDIN, DOSEL0, DOSEL1)
• The LC890561W has SDIN which is serial digital audio data input pin and makes input of 24bit data possible.
• The format of the serial audio data input into SDIN should be adjusted to the same format as the demodulated data
output. Therefore, the input format of SDIN is the same as the setup of DOSEL0 and DOSEL1 terminals, and the
DOSW command.
• The SDIN data to be input should be in synchronization with BCK and LRCK clock.
• SDIN input data is output to DATAO and DATAO2 behind two frames since it is latched to shift register.
• When not using the SDIN terminal, it is connected to GND.
