9 / 71 page DS721A6 9 CS42324 MUTEC2 12 Mute Control 2 (Output) - Active-low mute output can drive external circuitry to eliminate the clicks and pops associated with any single-rail output. This pin will become a high-impedance out- put during power-down mode or when an invalid MCLK to LRCK ratio is detected. MUTEC3 13 Mute Control 3 (Output) - Active-low mute output can drive external circuitry to eliminate the clicks and pops associated with any single-rail output. This pin will become a high-impedance out- put during power-down mode or when an invalid MCLK to LRCK ratio is detected. VCMBUF 14 VCMBUF (Output) - Internally buffered VCMDAC VCMDAC 15 DAC Common-Mode Voltage (Output) - Filter connections for the DAC internal quiescent refer- ence voltage. VA_H 16 18 Analog High Voltage Power (Input) - Positive power for the internal output buffer section. GNDH 17 Analog Ground (Input) - Ground reference for high-voltage section. AOUT1A, AOUT1B AOUT2A, AOUT2B AOUT3A, AOUT3B 19, 20 21, 22 23, 24 DAC Analog Audio Outputs (Output) - The full-scale output level is specified in the DAC Analog Characteristics specification table. AIN5B, AIN5A AIN4B, AIN4A AIN3B, AIN3A AIN2B, AIN2A AIN1B, AIN1A 25, 26 27, 28 29, 30 31, 32 33, 34 Stereo Analog Inputs 1-5 (Input) - The full-scale input level is specified in the ADC Analog Char- acteristics specification table. RST 35 Reset (Input) - The device enters a low-power mode when this pin is driven low. OVFL 36 ADC Overflow (Output) - Indicates an ADC overflow condition is present. SDIN2 SDIN1 37 38 Serial Audio Data Input (Input) - Input for two’s complement serial audio data. MCLK2 39 Master Clock 2 (Input) - Optional asynchronous clock source for the DAC’s delta-sigma modula- tors. LRCK2 40 Serial Port 2 Left/Right Clock (Input/Output) - Determines which channel, Left or Right, is cur- rently active on the serial audio input data line. SCLK2 41 Serial Port 2 Serial Bit Clock (Input/Output) - Serial bit clock for serial audio interface 2. VD 42 Digital Power (Input) - Positive power for the internal digital section. GND 43 Digital Ground (Input) - Ground reference for the internal digital section. VL 44 Digital Interface Power (Input) - Determines the required signal level for the control and serial port interfaces as shown in “I/O Power Rails” on page 12. Refer to the“Recommended Operating Conditions” on page 13 for appropriate voltages. SDOUT 45 Serial Audio Data Output (Output) - Output for two’s complement serial audio data. SCLK1 46 Serial Port 1 Serial Bit Clock (Input/Output) - Serial bit clock for serial audio interface 1. LRCK1 47 Serial Port 1 Left/Right Clock (Input/Output) - Determines which channel, Left or Right, is cur- rently active on the serial audio output data line. MCLK1 48 Master Clock 1 (Input) - Clock source for the ADC’s delta-sigma modulators. By default, this sig- nal also clocks the DAC’s delta-sigma modulators. |
