Primary Interface Digital Audio Serial Data DAC Input. Voiceband filtering available on this
input.
Primary Interface Digital Audio Serial Data ADC Output. Voiceband filtering available on
this output.
Primary Interface Digital Audio Bit Clock Input/Output. BCLKS1 is an input when the
MAX9851/MAX9853 is in slave mode and an output when in master mode.
Primary Interface Digital Audio Left-Right Clock Input/Output. LRCLKS1 is the audio
sample rate clock and determines whether the audio data on SDINS1 is routed to the left
or right channel. LRCLKS1 is an input when the MAX9851/MAX9853 is in slave mode and
an output when in master mode.
