Part Number: DS90UB948-Q1 Dears: Our design meet some issues about DS90UB948 and DS90UB947. Firstly, is there Errata about DS90UB948 and DS90UB947? Secondly, during the PP testing in Cars the Infotainment will happen snow dot in screen or screen...

 Can we reset PDB several times? If we can how could we do?

And another issue is when does 947 send data to 948 after 947 receives clock signal or DE signal?

Is there any requirement about 947 sending data to 948?

Pls. kindly help us!

Thanks a lot!

Best regards
