Part Number: SN65DP141
I have an OpenLDI link that routes through 4 connectors and over 16" of PCB routing. Since we recommend no more than 10" for this interface, I need a re-driver device The SN65DP141 was recommended to me as a candidate. This seems excessive for a link running under 3Gbps. Can you recommend an optimal choice for Open LDI?

In reply to Francisco Javier Zamudio:
The Open LDI interface is an LVDS interface that has 4 data pairs and a clock pair as a uni-directional interface. The clock pair operates at a pixel clock rate which is 1/7 of the data bit rate. The DPxxx parts recommended all only have 4 pairs. Do you still think these are the best solution or can you recommend a different solution that will support all 5 pairs?
In reply to Tom Johnson 16214:
We are currently considering the DS25BR440 to perform the re-driver functionality for the 4 data pairs and the DS10BR150 for the clock since we are told that it has the same propagation delay as the BR440. Can you confirm that this is a reasonable solution for extending the length for an Open LDI interface operating with a pixel clock up to 170MHz and data at up to 1000Mbps per lane?
We do not want to use a concentrater like the DS90UB947 device. We want to maintain the signal in the Open LDI format.
