When using the DisplayPort Receiver Subsystem v2.0 (Rev 3), how do I use the DP159 forwarded clock at 1.62 Gbps for Kintex UltraScale parts?
In Kintex UltraScale parts, the DP159 is not used for operation at 1.62 Gbps. This will be resolved in Vivado 2017.1 and later versions.
There is a software patch that is available that allows the DP159 forwarded clock to be used instead of the 270 MHz on-board reference clock. This will help with training of DisplayPort lane rates at 1.62 Gbps.
Vivado 2016.4 users will need the following patch:
