I2C for DLP LightCrafter Display 3010 EVM

Hello NOVA17,

Specific to the  DLP LightCrafter Display 3010 EVM, we use pullup supply of 1.8V for the IIC0_SDA & IIC0_SCL lines (referenced in link to schematic below).  In general, the DLPC3433/8 device can use VCC_INTF equal to 1.8V-3.3V range to specify the logic voltage level.  This gives some flexibility if you choose a front-end processor/peripherals that uses a different TTL logic level.  You might reference VCC_INTF in the dlpc3438 datasheet, for more on this.

The EDID on the HDMI to the ITE device uses 5V logic (RX_DDCSDA0 & RX_DDCSCL0 in schematic below). 

The schematics are available in the Reference Designs page on the 3010EVM website.

If you have any further questions, please do not hesitate to ask.
