Part Number: SN75DP130

Hi Sirs,

Sorry to bother you.

We would like to know does DP130 have support eDP signal?

We finished schematic as below, could you help double confirm it?

Any suggestion are welcome.

DP130 supports eDP application.

Any reason why you are using dual supply DP130(DP130DS) instead single supply DP130 (DP130SS)?

On the schematic:
CAD_SNK needs to be pulled low through 1M resistor.
SCL_CTL and SDA_CTL need to be pulled up to 3.3V through 2k resistor.
Instead capacitor on EN, put a 4.7K pullup to 3.3V on EN.

Thanks
David

Hi David,
Because DP130DS already in our internal part pool, so we choose it.
Any risk on this parts??

Thanks!!

There is no problem using DP130DS, please make sure you are following the power sequence as outlined in section 11 of the datasheet.

Thanks
