SN75DP130 in a sink mode , using xilinx displayport ip(v7.0) link training part of the failure

Hi,

When using SN75DP130 in a sink application is recommended to configure it via I2C, using link training could result in inappropriate configuration of DP130.

Yes DP159 has better performance. DP159 is intended for DP++ to HDMI2.0 level translation, there is a special mode where you could use it as DP retimer.

You may try a fixed configuration of DP130 first, if this is not enough move to DP159.

hi ,Moises Garcia

1. The DP159 device supports 4K x 2K @60Hz  10/12bit color depth ? or  only support  8bit  color depth at 4K x 2K @60Hz?

2.The DP130 plan to upgrade the performance in the future?

thanks!!!

Hi Doph,

DP130 and DP159(x-mode) support the same data rate up to 5.4Gbps

To have 4k2k@60Hz 10/12bit you need DP1.3 to use data rates faster than 5.4Gbps,

Currently we have SN65DP141 for DP1.3

hi ， Moises 

thanks for your answer!

DP141 can handle sources with SSC(spread spectrum clocking )  and high gitter ?

ATI Firepro is probably SSC based .

thanks!!!

Hi， Moises

thanks for your answer !

In the DP159 datasheet ,“When working as a retimer, the embedded clock data recovery (CDR) cleans up the  input high frequency and random jitter from video source” .

But DP130/DP141 is not the retimer.

Do you have any other chip recommended in the DisplayPort  receiver application, not only supports 4K x 2K @60Hz  10/12bit color depth ,but also cleans up the  input high frequency similar as the DP159's retimer ? because I must use Xilinx gtx.

thanks !!!

Hi Doph,

You could try DP159, this is the application note to use it as a DP retimer(x mode).
