DESCRIPTION
Serial audio data clock (shift clock). SCLK is the serial audio port
input data bit clock.
I
2
C serial control data interface input/output
Serial audio data 1 input is one of the serial data input ports. SDIN1
supports three discrete (stereo) data formats.
Serial audio data 2 input is one of the serial data input ports. SDIN2
supports three discrete (stereo) data formats.
Controls ramp time of OUT_X for pop-free operation. Leave this pin
floating for BD mode. Requires capacitor of 2.2 nF to GND in AD
mode. The capacitor determines the ramp time of PWM outputs from
0% to 50%. For 2.2 nF, start/stop time is ~10 ms.
Test pin. Connect directly to GND.
Subwoofer negative PWM output
Subwoofer positive PWM output
Test pin. Connect directly to GND.
Test pin. Connect directly to DVDD.
Output indicating validity of ALL PWM channels, active-high. This pin
is connected to an external power stage. If no external power stage is
used, leave this pin floating.
Internally regulated 1.8-V analog supply voltage. This terminal must
not be used to power external devices.
Internally regulated 1.8V digital supply voltage.This terminal must not
be used to power external devices.
3.3 Regulator output. Not to be used as s supply or connected to any
other components other than decoupling caps. Add decoupling
capacitors with pins 42 and 41.

Stresses beyond those listed under
absolute ratings
may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under
recommended operation conditions
are
not implied. Exposure to absolute-maximum conditions for extended periods may affect device reliability.
5-V tolerant inputs are PDN, RESET, MUTE, SCLK, LRCLK, MCLK, SDIN1, SDIN2, SDA, SCL, and HPSEL.
DC voltage + peak ac waveform measured at the pin should be below the allowed limit for all conditions.
