Pin Functions

PIN TYPE 5-V
TOLERANT		 TERMINATION DESCRIPTION
NAME NO.
ASEL_EMO2 10 DIO Pullup I2C Address Select. Address will 0X34/0X36 with the value of pin being "0' or "1" during de-assertion of reset. Can be programmed to be an output (as energy manager output for subwoofer)
AVDD 9 P Analog supply (3.3 V) for PLL.
AVDD_PWM 50 P 3.3-V analog power supply for PWM. This terminal can be connected to the same power source used to drive power terminal DVDD; but to achieve low PLL jitter, this terminal should be bypassed to AVSS_PWM with a 0.1-μF low-ESR capacitor.
AVSS 5 P Analog ground
AVSS_PWM 51 P Analog ground for PWM. Must have direct return Cu path to analog 3.3V supply for optimized performance.
BKND_ERR 34 DI Pullup Active-low. A back-end error sequence is generated by applying logic low to this terminal. The BKND_ERR results in no change to I2C parameters, with all H-bridge drive signals going to a hard-mute state (Non PWM Switching).
DVDD1 35 P 3.3-V digital power supply. (It is recommended that decoupling capacitors of 0.1 μF and 10 μF be mounted close to this pin).
DVDD2 14 P 3.3-V digital power supply for PWM. (It is recommended that decoupling capacitors of 0.1 μF and 10 μF be mounted close to this pin).
DVSS1 36 P Digital ground 1
DVSS2 13 P Digital ground 2
EMO1 15 DO Energy Manger Output interrupt - Asserted high when threshold is exceeded.
HP_SEL 17 DI 5 V Pullup Headphone/speaker selector. When a logic low is applied, the headphone is selected (speakers are off). When a logic high is applied, speakers are selected (headphone is off).
LRCLK 22 DI 5 V Pulldown Serial-audio data left/right clock (sampling-rate clock)
LRCLKO / LRCKIN_2 31 DIO 5V Pulldown LRCLK for I2S OUT. Can also be used as LRCKIN_2 (I2S Input for SDIN2_x and SRC Bank 2)
MLCK 11 DI 3.3-V master clock input. The input frequency of this clock can range from 2 MHz to 50 MHz.
MUTE 19 DI 5 V Pullup Soft mute of outputs, active-low (muted signal = a logic low, normal operation = a logic high). The mute control provides a noiseless volume ramp to silence. Releasing mute provides a noiseless ramp to previous volume.
OSCRES 12 DO 18k resistor to GND Oscillator resistor (1% tolerance).
PDN 18 DI 5 V Pullup Power down, active-low. PDN powers down all logic and stops all clocks whenever a logic low is applied. The I2C parameters are preserved through a power-down cycle, as long as RESET is not active.
PLL_FLTM 6 AIO PLL negative filter.
PLL_FLTP 7 AIO PLL positive filter.
PSVC/MCLKO 33 DO Power-supply volume control PWM output or MCKO for external ADC (SDIN5 Source)
PWM_HPM_L 1 DO PWM left-channel headphone (differential –)
PWM_HPM_R 3 DO PWM right-channel headphone (differential –)
PWM_HPP_L 2 DO PWM left-channel headphone (differential +)
PWM_HPP_R 4 DO PWM right-channel headphone (differential +)
PWM_M_1 38 DO PWM 1 output (differential –)
PWM_M_2 40 DO PWM 2 output (differential –)
PWM_M_3 42 DO PWM 3 output (differential –)
PWM_M_4 44 DO PWM 4 output (differential –)
PWM_M_5 53 DO PWM 5 output (lineout L) (differential –)
PWM_M_6 55 DO PWM 6 output (lineout R) (differential –)
PWM_M_7 46 DO PWM 7 output (differential –)
PWM_M_8 48 DO PWM 8 output (differential –)
PWM_P_1 39 DO PWM 1 output (differential +)
PWM_P_2 41 DO PWM 2 output (differential +)
PWM_P_3 43 DO PWM 3 output (differential +)
PWM_P_4 45 DO PWM 4 output (differential +)
PWM_P_5 54 DO PWM 5 output (lineout L) (differential +)
PWM_P_6 56 DO PWM 6 output (lineout R) (differential +)
PWM_P_7 47 DO PWM 7 output (differential +)
PWM_P_8 49 DO PWM 8 output (differential +)
RESET 16 DI 5 V Pullup System reset input, active-low. A system reset is generated by applying a logic low to this terminal. RESET is an asynchronous control signal that restores the TAS5558 to its default conditions, sets the valid output low, and places the PWM in the hard-mute state (Non PWM Switching). Master volume is immediately set to full attenuation. On the release of RESET, if PDN is high, the system performs a 4- to 5-ms device initialization and sets the volume at mute.
SCL 21 DI 5 V I2C serial-control clock input/output
SCLK 23 DI 5 V Pulldown Serial-audio data clock (shift clock) input
SCLKO / SCLKIN_2 30 DIO 5V Pulldown Serial data clock out. I2S bit clock out. Can also be used as SCLKIN_2 (I2S Input for SDIN2_x and SRC Bank 2)
SDA 20 DIO 5 V I2C serial-control data-interface input/output
SDIN1 24 DI 5 V Pulldown Serial-audio data bank 1 input 1 is one of the serial-data input ports and goes into the 1st SRC Bank. Four discrete (stereo) data formats and is capable of inputting data at 64 fS.
SDIN2 25 DI 5 V Pulldown Serial-audio data bank 1 input 2 is one of the serial-data input ports and goes into the 1st SRC Bank. Four discrete (stereo) data formats and is capable of inputting data at 64 fS.
SDIN2-1 26 DI 5 V Pulldown Serial-audio data bank 2 input 1 is one of the serial-data input ports and goes into the 2nd SRC Bank. Four discrete (stereo) data formats and is capable of inputting data at 64 fS.
SDIN2-2 27 DI 5 V Pulldown Serial-audio data bank 2 input 2 is one of the serial-data input ports and goes into the 2nd SRC Bank. Four discrete (stereo) data formats and is capable of inputting data at 64 fS.
SDOUT / SDIN5 29 I2S data out or SDIN5 (must be sync'd to post SRC rate). Usually used for Microphone ADC Input
TEST 32 DI Test mode active high. In normal mode tie this to digital ground.
VALID 37 DO Output indicating validity of PWM outputs, active-high
VR_DIG 28 P Voltage reference for 1.8-V digital core supply. A pinout of the internally regulated 1.8-V power used by digital core logic. A 4.7-μF low-ESR capacitor should be connected between this terminal and DVSS. This terminal must not be used to power external devices.
VR_PWM 52 P Voltage reference for 1.8-V digital PLL supply. A pinout of the internally regulated 1.8-V power used by digital PLL logic. A 0.1-μF low-ESR capacitor should be connected between this terminal and DVSS_CORE. This terminal must not be used to power external devices.
