TDP158: HDMI Pre-emphasis

Part Number: TDP158

Hi, Team,

 

My customer is using TDP158 for the following application. HDMI->TDP158->HDMI connector

 

-For HDMI redriver mode, can TDP158 enable Pre-emphasis? I'm checking the section 9 of datasheet. There is following description "Pre-emphasis is not implemented on the clock lane unless the TDP158 is in DP Mode and at which time it becomes a data lane.". In my understanding, TDP158 cannot enable Pre-emphasis but I would like to double check.

 

Best Regards,

    In HDMI mode, pre-emphasis applied to the three data lanes, it does not apply to the clock lane.

    In DP mode, there is no clock lane, the clock lane became a data lane, then pre-emphasis applies to all four data lanes.

    Thanks
