hi aasif bashir dar,
the data rate of the layout of system should be always graeter than data rate of the bit sequence of PBRS.
talking aboout the example you posted
that if sweep to data rate of PBRS as;
1gbps,5gbps,10gbps, 15gbps……..35gbps,40gbps…
then your layout data can be kept 40gbps or greater than 40 gbps for all sweeps..
with regards
