I think I understand now. Your post and the "details" description of this field is very poorly worded, making it confusing and ambiguous.
The quote from the IP generator help says "Example: A PLL data rate of "10000 Mbps" and a local division factor of 8 results in a channel data rate of "1250 Mbps." I don't think this is technically wrong, but it does make it seem like the channel data rate is calculated and derived based on this setting ("results in"), when in reality it adjusts the required input clock frequency from a PLL, and the channel data rate will still be whatever you typed into the "Data Rate" field. Maybe this would be more clear:
"The TX local clock division factor adjusts the required PLL clock frequency value needed to achieve the specified channel data rate."
I guess another point of confusion is that I have never heard a PLL output defined in terms of "Mbps". Isn't the output of a PLL just a clock? Aren't clocks usually defined in terms of Hz?
