6 / 53 page  CS4272 6 DS593F1 Pin Name # Pin Description XTO XTI 1,2 Crystal Connections (Input/Output) - I/O pins for an external crystal which may be used to generate MCLK. See “Crystal Applications (XTI/XTO)” on page 24 or “Crystal Applications (XTI/XTO)” on page 27. MCLK 3 Master Clock (Input/Output) -Clock source for the delta-sigma modulators. See “Crystal Applications (XTI/XTO)” on page 24 or “Crystal Applications (XTI/XTO)” on page 27. LRCK 4 Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the serial audio data line. SCLK 5 Serial Clock (Input/Output) - Serial clock for the serial audio interface. SDOUT 6 Serial Audio Data Output (Output) - Output for two’s complement serial audio data. SDIN 7 Serial Audio Data Input (Input) - Input for two’s complement serial audio data. DGND 8 Digital Ground (Input) - Ground reference for the internal digital section. VD 9 Digital Power (Input) - Positive power for the internal digital section. VL 10 Logic Power (Input) - Positive power for the digital input/output interface. SCL/CCLK 11 Serial Control Port Clock (Input) - Serial clock for the serial control port. SDA/CDIN 12 Serial Control Data (Input/Output) - SDA is a data I/O in I²C mode. CDIN is the input data line for the control port interface in SPI mode. AD0/CS 13 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 format. RST 14 Reset (Input) - The device enters a low power mode when this pin is driven low. VCOM 15 Common Mode Voltage (Output) - Filter connection for internal common mode voltage. AINA- AINA+ AINB+ AINB- 16, 17, 18, 19 Differential Analog Input (Input) - The full scale differential input signals are presented to the delta- sigma modulators. The full scale level is specified in the ADC Analog Characteristics specification table. VA 20 Analog Power (Input) - Positive power for the internal analog section. AGND 21 Analog Ground (Input) - Ground reference for the internal analog section. FILT+ 22 Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits. AMUTEC 23 Channel A Mute Control (Output) - This pin is active during power-up initialization, reset, muting, when master clock to left/right clock frequency ratio is incorrect, or power-down. AOUTA- AOUTA+ AOUTB+ AOUTB- 24, 25, 26, 27 Differential Analog Audio Output (Output) - The full scale differential output level is specified in the DAC Analog Characteristics specification table. BMUTEC 28 Channel B Mute Control (Output) - This pin is active during power-up initialization, reset, muting, when master clock to left/right clock frequency ratio is incorrect, or power-down. |
