SN75DP139: Hardware control

Roy Chou1

Part Number: SN75DP139

Hi Team,

My customer would like to transfer the signal from DP to HDMI. I find the SN75DP139 solution.

Could you let me know if the signal could transfer automatically by connecting the DP signal and only controlled by pin or it needs the software control effort?

Regards,

Roy

DP or DP++? DP139 is a DP++ to HDMI level shifter, it will not support DP.

Thanks

Hi David,

It's typo. Customer would like to transfer the signal from DP++ to HDMI. Could you let me know if the signal could transfer automatically by connecting the DP++ signal and only controlled by pin or it needs the software control effort?

In addition, do we have DP to HDMI solution, too?

Regards,

Roy

You can configure the DP139 using the pin configuration, please refer to Table 1 in the DP139 datasheet for the control pin lookup table.

The DP139 can only support up to HDMI1.4b, does the customer need the HDMI2.0 support?

Unfortunately, we do not have a DP to HDMI solution.

Thanks

David
