Right-Channel Headphone Output
S1 Digital Audio Bit Clock Input/Output. BCLKS1 is an input when the MAX9888 is in slave mode and
an output when in master mode. The input/output voltage is referenced to DVDDS1.
S1 Digital Audio Left-Right Clock Input/Output. LRCLKS1 is the audio sample rate clock and
determines whether S1 audio data is routed to the left or right channel. In TDM mode, LRCLKS1 is a
frame sync pulse. LRCLKS1 is an input when the MAX9888 is in slave mode and an output when in
master mode. The input/output voltage is referenced to DVDDS1.
S1 Digital Audio Serial-Data DAC Input. The input voltage is referenced to DVDDS1.
Jack Sense. Detects the insertion of a jack. See the Headset Detection section.
Single-Ended Line Input B1. Also negative differential line input B.
Single-Ended Line Input A2. Also positive differential line input A or negative differential external
microphone input.
