8 / 68 page 8 DS792F1 CS43L22 Confidential Draft 10/7/08 1.1 I/O Pin Characteristics Input and output levels and associated power supply voltage are shown in the table below. Logic levels should not exceed the corresponding power supply voltage. AGND 17 Analog Ground (Input) - Ground reference for the internal analog section. FILT+ 18 Positive Voltage Reference (Output) - Filter connection for the internal sampling circuits. VQ 19 Quiescent Voltage (Output) - Filter connection for the internal quiescent voltage. TSTO 20,36 Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no connection external to the pin). AIN4A,B AIN3A,B AIN2A,B AIN1A,B 21,22 23,24 25,26 29,30 Line-Level Analog Inputs (Input) - Single-ended stereo line-level analog inputs. AFILTA,AFILTB 27,28 Anti-alias Filter Connection (Output) - Anti-alias filter connection for analog passthrough mode. SPKR/HP 31 Speaker/Headphone Switch (Input) - Powers down the left and/or right channel of the speaker and/or headphone outputs. RESET 32 Reset (Input) - The device enters a low power mode when this pin is driven low. VL 33 Digital Interface Power (Input) - Determines the required signal level for the serial audio inter- face and host control port. VD 34 Digital Power (Input) - Positive power for the internal digital section. DGND 35 Digital Ground (Input) - Ground reference for the internal digital section. MCLK 37 Master Clock (Input) - Clock source for the delta-sigma modulators. SCLK 38 Serial Clock (Input/Output) - Serial clock for the serial audio interface. SDIN 39 Serial Audio Data Input (Input) - Input for two’s complement serial audio data. LRCK 40 Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the serial audio data line. GND/Thermal Pad - Ground reference for PWM power FETs and charge pump; thermal relief pad for optimized heat dissipation. Power Supply Pin Name I/O Internal Connections Driver Receiver VL RESET Input - - 1.65 V - 3.47 V, with Hysteresis SCL Input - - 1.65 V - 3.47 V, with Hysteresis SDA Input/ Output - 1.65 V - 3.47 V, CMOS/Open Drain 1.65 V - 3.47 V, with Hysteresis MCLK Input - - 1.65 V - 3.47 V LRCK Input/ Output Weak Pullup (~1 M Ω) 1.65 V - 3.47 V, CMOS 1.65 V - 3.47 V SCLK Input/ Output Weak Pullup (~1 M Ω) 1.65 V - 3.47 V, CMOS 1.65 V - 3.47 V SDIN Input - - 1.65 V - 3.47 V VA SPKR/HP Input - - 1.65 V - 2.63 V VP SPKR_OUTA+ Output - 1.6 V - 5.25 V Power MOSFET - SPKR_OUTA- Output - 1.6 V - 5.25 V Power MOSFET - SPKR_OUTB+ Output - 1.6 V - 5.25 V Power MOSFET - SPKR_OUTB- Output - 1.6 V - 5.25 V Power MOSFET - |
