VA 32 Analog Power (Input) - Positive power supply for the analog section. Refer to the Recommended Operating Conditions for appropriate voltages. VLS 43 Serial Audio Interface Power (Input) - Determines the required signal level for the serial audio interface. Refer to the Recommended Operating Conditions for appropriate voltages. TST_OUT 23, 26 27, 30 33, 36 37, 40 Test Output - These pins need to be floating and not connected to any trace or plane. Hardware Mode Definitions M0 M1 M2 M3 M4 17 16 15 12 10 Mode Selection (Input) - Determines the operational mode of the device as detailed in Tables 4 and 5. Software Mode Definitions SCL/CCLK 15 Serial Control Port Clock (Input) - Serial clock for the serial control port. Requires an external pull-up resistor to the logic interface voltage in I²C® mode as shown in the Typical Connection Dia- gram. SDA/CDIN 16 Serial Control Port Data (Input/Output) - SDA is a data I/O line in I²C mode and is open drain, requiring an external pull-up resistor to the logic interface voltage, as shown in the Typical Con- nection Diagram; CDIN is the input data line for the control port interface in SPI™ mode. AD0/CS 17 Address Bit 0 (I²C) / Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in I²C mode; CS is the chip select signal for SPI mode. TST 10 12 Test - These pins need to be tied to analog ground. DSD Definitions DSD1, DSD2 DSD3, DSD4 DSD5, DSD6 DSD7, DSD8 3, 2 1, 48 47,46 45, 44 Direct Stream Digital Input (Input) - Input for Direct Stream Digital serial audio data.
