DM648 REFCLK Jitter Requirements

For REFCLKP/N clock rate the possible suggested is either 50MHz or 62.5MHz or 125MHz, and the corresponding Line Rate is 625Mbps or 1250Mbps.

1.4 Clocks (Page 19)

Does the 50 ps pk-pk apply regardless of which reference clock rate is used?
If not, what is the jitter requirement for each reference clock rate?

Does the 50 ps pk-pk apply to the 625Mbps line rate?
If not, what is the jitter requirement for the 625Mbps line rate?
