Part Number: SN65DP159

Hi Sir,

We are searching for an I2C-over-AUX to DDC bridge IC for MCU to access EDID from eDP panel.

Can you use this specific function inside SN65DP159 and have others N.C? Or any other parts more suitable?

Thanks,

Why do you need I2C-over_AUX to DDC bridge for an eDP panel? eDP panel should communicate using the AUX channel only?

Thanks

Hi David

I have a project that needs to develop a USBC DP ALT monitor. We'd like to use an MCU instead of a scaler for LCD brightness control. MCU only has I2C interfaces, so an I2C-over-AUX to DDC bridge is required for accessing EDID in the eDP panel. For EDID content, the AUX channel is the only way.

Thanks for your help.

We do not have a stand-alone I2C-over-AUX bridge device. DP159 is probably the best solution to accomplish this.

Thanks

Thanks David, We plan to ask some samples for testing first.
