I am using one AD9517-0 LVPECL output to drive a fanout buffer to convert the signal to two LDVS signals.
In the AD9517-0 datasheet I can see this figure to interface LVPECL stages:
On the other hand, in the datasheet of the fanout buffer, I can see this other configuration:
My dessign follows the AD recomendation (first schematic) and incorporates R1 to R4 of the second schematic.
Question: Should I keep the 100 Ohn resistor at the imput of the receiver (as proposed in the AD schematic)?
Thanks in advance
