Hi team,

My customers wonder which 948 register can tell the signal quality is poor or lane is disconnected? Appreciate your guidance!

Hi,

to determine the FPD-Link signal quality of your system you can run BIST mode or you can use the Margin Analysis Program described in this document: https://www.ti.com/lit/ug/snlu243/snlu243.pdf?ts=1628525775365&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDS90UB948-Q1
