Hi,
I am presently working on a design involving a RocketIO in a Virtex II
Pro. I am looking at reference clocks for the PLL of the RocketIO
meeting among other things the jitter requirement related to the serial
link frequency. I am wondering how to combine deterministic jitter and
random jitter parameters of the oscillator. Is the total jitter the rms
value of the two parameters or do I need to add the maximums of each
parameter ? Doesn't the answer depend on the device receiving the clock
and therefore the way it deals with jitter ?
Thanks,
JF
