Hi, we use DS90UB947-Q1as Ser and use DS90UB948-Q1 as Des in our display product.
1 Both +/-4KV ESD Contact Discharge test are failure, the phenomenon is that the dispay picture appears to flicker.Now we have updated a LAYOUT.
2 FDP_link is set to equal length. (Because the interface definition cannot be changed and the structure is limited,
I think the serpentine wiring in this part is not reasonable at present.
It's basically the same length, and the same distance is not well controlled.)Could you help to check the sch and pcb layout, and give us any suggestion?
Best regards
