5 / 40 page CS4392 DS459PP3 5 1. PIN DESCRIPTION - PCM DATA MODE RST 1 Reset (Input) - Powers down device and resets all internal registers to their default settings. VL 2 Logic Power (Input) - Positive power for the digital input/output. SDATA 3 Serial Audio Data (Input) - Input for two’s complement serial audio data. SCLK 4 Serial Clock (Input/Output) - Serial clock for the serial audio interface. LRCK 5 Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the serial audio data line. MCLK 6 Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters. FILT+ 11 Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits. CMOUT 12 Common Mode Voltage (Output) - Filter connection for internal quiescent voltage. AMUTEC BMUTEC 20 13 Mute Control (Output) - The Mute Control pin goes high during power-up initialization, reset, muting, power-down or if the master clock to left/right clock frequency ratio is incorrect. AOUTB- AOUTB+ AOUTA+ AOUTA 14 15 18 19 Differential Analog Output (Outputs) - The full scale differential analog output level is specified in the Analog Characteristics specification table. AGND 16 Ground (Input) VA 17 Analog Power (Input) - Positive power for the analog section. Control Port Mode Definitions M3 7 Mode Selection (Input) - This pins should be tied to GND level during control port mode. SCL/CCLK 8 Serial Control Port Clock (Input) - Serial clock for the serial control port. SDA/CDIN 9 Serial Control Data (Input/Output) - SDA is a data I/O line 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/Output) - AD0 is a chip address pin in I2C mode; CS is the chip select signal for SPI format. Stand-Alone Mode Definitions M3 M2 M1 M0 7 8 9 10 Mode Selection (Input) - Determines the operational mode of the device.
