Need eye mask for DS90CR484

Other Parts Discussed in Thread: DS90CR484

Hi,

I am using DS90CR484 in the design. Previously we were using 5 meter 3M cable for the communication. Now we have a plan to look for alternate vendor. To qualify the cable, I need to create eye pattern for DS90CR484. From the datasheet I could not find out the LVDS signal risetime/fall time. Could you please help me to create the eye pattern?.

thanks,

Latha

    Hi Latha,

    I checked on this. 

    Please note data sheet Transmitter Switching Characteristics for the rise/fall time(LHLT and LLHT parameters). Also, Output voltage swing is about 350mV differential. We also have the IBIS file describing I vs V characteriztics.
