DS90UH948-Q1: display timing from 947input and 948output

Part Number: DS90UH948-Q1


Hi Team,

I have two scenario would like to check with you. 

1. dual oLDI input(D0-D7) -> 947 <-> 948 -> dual oLDI output(D0-D7) -> display

In this scenario, we can expect that dual oLDI input(D0-D3 and D4-D7) display timing input to 947 is the same as 948 dual oLDI output(D0-D3 and D4-D7). Is it correct?

2.  single oLDI input(D0-D7) -> 947 <-> 948 -> dual oLDI output(D0-D7) -> display

In this scenario, we can expect that single oLDI input(D0-D3) display horizontal timing input to 947 is the 2 times to 948 dual oLDI output(D0-D3 and D4-D7). Is it correct?

I draw the diagram below that you could understand more detailed. Please let me know if there is any question. For scenario.2 , can we say Serdes bypass the display timing because the in/out display timing will be the same.

Regards,

Roy
