9 / 57 page STA328 Pin out 9/57 2.3 Pin description OUT1A, 1B, 2A and 2B (pins 16, 10, 9 and 3) Output half bridge PWM outputs 1A, 1B, 2A and 2B provide the input signals to the speakers. RESET (pin 22) Driving RESET low sets all outputs low and returns all register settings to their default (reset) values. The reset is asynchronous to the internal clock. 15 I/O VCC1A Positive supply 16 O OUT1A Output half bridge 1A 17 I/O GND_CLEAN Logical ground 18 I/O GND_REG Substrate ground 19 I/O VDD_REG Logic supply 20 I/O VL Logic supply 21 I CONFIG Logic levels 22 I RESET Reset 23 I SCL I2C serial clock 24 I/O SDA I2C serial data 25 - RESERVED This pin must be connected to GND 26 I PLL_FILTER Connection to PLL filter 27 I XTI PLL input clock 28 I/O GNDA Analog ground 29 I/O VDDA Analog supply, nominally 3.3 V 30 I SDI I2S serial data channels 1 & 2 31 I/O LRCKI I2S left/right clock, 32 I BICKI I2S serial clock 33 I/O GND Digital ground 34 I/O VDD Digital supply, nominally 3.3 V 35 I/O VSS 5 V regulator referred to +VCC 36 I/O VCC_SIGN 5 V regulator referred to ground Table 2.
