6 / 67 page  CS42418 6 1 PIN DESCRIPTIONS Pin Name # Pin Description DAC_SDIN1 DAC_SDIN2 DAC_SDIN3 DAC_SDIN4 1 64 63 62 DAC Serial Audio Data Input ( Input) - Input for two’s complement serial audio data. DAC_SCLK 2 DAC Serial Clock (Input/Output) - Serial clock for the DAC serial audio interface. DAC_LRCK 3 DAC Left Right Clock ( Input/Output) - Determines which channel, Left or Right, is currently active on the DAC serial audio data line. VD 4 51 Digital Power ( Input) - Positive power supply for the digital section. DGND 5 52 Digital Ground ( Input) - Ground reference. Should be connected to digital ground. VLC 6 Control Port Power ( Input) - Determines the required signal level for the control port. SCL/CCLK 7 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 Diagram. SDA/CDOUT 8 Serial Control Data ( Input/Output) - SDA is a data I/O line in I2C mode and requires an external pull-up resistor to the logic interface voltage, as shown in the Typical Connection Diagram. CDOUT is the output data line for the control port interface in SPI mode. AD1/CDIN 9 Address Bit 1 (I2C)/Serial Control Data (SPI) ( Input) - AD1 is a chip address pin in I2C mode; CDIN is the input data line for the control port interface in SPI mode. AD0/CS 10 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 in SPI mode. INT 11 Interrupt (Output) - The CS42418 will generate an interrupt condition as per the Interrupt Mask register. See “Interrupts” on page 28 for more details. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 1 7 18 19 20 21 22 23 24 25 2 6 27 28 29 3 0 31 32 64 6 3 6 2 6 1 60 59 58 57 56 5 5 54 53 52 5 1 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 DAC _SDIN1 VD DG ND VLC SC L/CC LK SDA/CD O UT AD 1/CDIN AD0/CS INT RST AINR - AIN R+ AIN L+ AINL - AO UTA2- AOU TB1- AO UTB1+ AO UTA1+ AO UTA1- MU TEC AG N D VA GPO7 GPO6 GPO5 GPO4 GPO3 GPO2 GPO1 LPFL T DAC_ LRCK DAC _SCL K CS42418 |
