Part Number: DS90UH948-Q1

Hi Application team:

  Happy new year, I;m working with my customer review DS90UH948-Q1 Layout, I would like to know do you have like 948 as following PCB recommendation table ? 

if not , could you provide the Max value of trace length, intra-pair skew, inter-pair skew for FPD-LINK III ?

thank you

    Hi Roy,

    There is no maximum length because this depends on your board stack-up and how good the impedance of the trace is matched, but generally we recommend not exceeding 10cm.

    For the inter/intra pair skew requirements, it will ultimately depend on the tolerable skew for the receive side that 948 is connected to (display panel datasheet). When in doubt, we recommend to minimize as much as possible as good design practice to maximize system margin.

    Please see Layout section of the datasheet for the guidelines.

    Best,

    Josh

    Hi Josh:

       Got it and thank you for your information, I send datasheet PCB layout guide to customer already. 

    Let me resolved the E2E threads
