DRA72x EVM CPU Board User's Guide

3.15 Media Local Bus (MLB)

The EVM supports a Media Local Bus interface for connecting to external hardware (such as SMSC
OS81110/2+0 Physical Interface Board). The interface supports both 3-pin MediaLB and 6-pin
configurations.

Connector used: Samtec QSH-020-01-L-D-DP-A

3.16 Audio

The EVM supports onboard AIC3106 audio codec for analog audio conversions. Analog inputs are
supported on two 3.5-mm audio jacks, including stereo line inputs (P12) and mono microphone (P11).
Analog outputs are supported on two 3.5-mm audio jacks, providing stereo line outputs (P13) and stereo
headset (P14). The digital audio is connected to the SoC using multi-channel serial port (McASP3). The
codec requires a master clock (AHCLKX). The audio codec is configured using I2C1, and is accessed at
address 0x19.

3.17 COM8 Module Interface

A connector is provided to facilitate the plugging in of TI COM8Q modules, which provide features such as
Bluetooth and Wi-Fi™. The COM8Q interface requires a 3.6-V power supply; thus, a dedicated regulator
is provided. All signals on the COM8Q interface are required to 1.8 volts, thus voltage translators are
placed to convert from the standard IO levels of 3.3 V. UART interface (UART3) is used for BT-HCI port,
I2S port (McASP7) is used for BT-audio, and MMC4 port is use for WiFi communication.

Connector used: Samtec MEC6-150-02-S-D-RA1

3.18 User Interface LEDs

The CPU board has four user interface LEDs for debug, status indication, and so forth.

3.19 Power Monitoring

The CPU board has provisions to monitor power for many of the systems core power rails. The
measurement system is implemented using the TI INA226 I2C current shunt and power monitors. The
INA226 device monitors both the power supply voltage and shunt current measurements. Information is
connected from the INA226 devices using dedicated I2C buses. The INA226s can be controlled through
an off-board module (FTDI USART, MSP430, or a similar device).
