Hi,

Please kindly check if we can use the DS160PR412 and DS160PR421 for the below block diagram, thanks.

Hi Zhang,

The diagram looks OK to me. However it seems like devices do not use Port B and therefore the mux/demux switching feature is not used. Is there a reason for this? If there is no intention to use the mux/demux features in the future, then a normal redriver like the DS160PR410 would typically be simpler.

Best,

Evan Su

Hi Evan,

Thanks for you kindly support, and we have one problem that the DS160PR412 16Gbps PCIe rate is support for each linear redriver or total rate? thanks.

Dear customer,

I am following up on this issue. However, the relevant engineer is out of the office and you can expect a response to your thread by Jan 2nd.

Thank you

Hi Zhang,

PCIe data rates are given in GT/s (gigatransfers per second) and they are fixed depending on the generation. 16 GT/s is the data rate for PCIe Gen 4, meaning that the frequency of the bit patterns when looking at a channel is 16 GHz.

Best,

Evan Su
