The I2S header pins are used for three purposes: probing I2S signals coming out of PCM9211, bypassing

I2S signals from TLV320AIC3262 and using the PCM9211 I2S signals, and bypassing I2S signals from

the TLV320AIC3262 and using an external I2S source.

The TAS5548 is used for PWM input devices such as the TAS5624. The TAS5548 is TI's latest 8-channel

PWM modulator and has dual ASRC with audio post processing. Please go to www.ti.com for more

information.

The PCM3168A takes analog inputs (AIN1 and AIN2) and routes them to the TLV320AIC3262. AIN1 is

converted to I2S and routed to TAS5548 and J1. There is also an analog switch (MUX2) that can route

analog input directly to DUT via J1.

The GPIO extender (TCA6424A – U8) is used for initialization of the multiplexors and discrete signals. It is

controlled from the PPC via I

The MSP430 is populated but is not programmed. It is used in place of a PC for specifically-designed

demonstrations using a combination of TI devices on the PPCMB and a DUT evaluation board or

reference boards.

This section describes the PPCMB setup and software installation. Since the PPCMB connects to one of

the DUT EVMs, it is necessary to show the connection in this section. The TAS5760xEVM is used for this

purpose.
