Digital Audio Interface
The MAX9880A’s dual digital audio interface supports a
wide range of operating modes to ensure maximum
compatibility. See Figures 1 to 5 for timing diagrams. In
master mode, the MAX9880A outputs LRCLK and
BCLK, while in slave mode they are inputs. When oper-
ating in master mode, BCLK can be configured in a
number of ways to ensure compatiblity with other audio
devices.
The MAX9880A has two sets of digital audio interface
pins, S1 and S2, that can be connected to one of two
digital audio paths, DAI1 or DAI2.
DAI1: Digital Audio Path 1 Operation
• DAC path with DR of 90dB and ADC path with DR of
82dB
• DAC path connectable to either S1 or S2
• ADC path connectable to either S1 or S2
• 8kHz to 48kHz sample rates
• I2S and TDM-compatible modes
• Voice filters or audio filter modes
DAI2: Digital Audio Path 2 Operation
• High-fidelity DAC path with DR of 96dB
• DAC path connectable to either S1 or S2
• 8kHz to 96kHz sample rates
• I2S and TDM-compatible modes
• Audio FIR filters
• No ADC clock control from DAI2 sample clock and
no voice filter modes available in DAI2
