SN65DSI83: Cannot meet Tr/Tf when use IBIS modeling data.

simulation with channel will be faster, spec data was took w/o channel.

Hello Brian,

So Do you mean this result is not a problem?? right??

Thank you.

Hello Brian,

I was told that customer added channel modeling for this simulation.

Simulation result is not a problem even its result has smaller tr/tf value than spec??

Or they should add more load on channel to meet this spec??

Could you pls kindly advise this??

Thank you.

Hi,

Which rise/fall time are you trying to meet as I don't see the rise/fall time being defined specifically for LVDS in the DS90UB927Q-Q1?

Do you also have the 100ohm termination included in the simulation?

Thanks

Hello David,

Yes, 927 SER doesn't care it. but SN65DSI83 shows Tr/Tf spec.

so customer concern any potential risk if customer doesn't meet. so they hope to check with team.

For your question, I confirmed they applied 100ohm termination for their simulation.

Thank you.
