Part Number: SN75DP130

Hi Sir 

If I use DP130 and pass displayport signal integrity 

How much output insertion loss that DP130 can be cover (I saw datasheet have input insertion loss data)

  • DP130 has four pre-emphasis levels with max level at 9.5dB. Assuming RX has no equalization capability, you should design output insertion loss within the 9.5dB.

    Thanks

    Hi David 

    I refer to figure 7 in DP130 datasheet ,so you mean DP130 pre channel could support 13dB loss and post channel could support 9.5dB ,is it correct ?

    Thanks
