Horizontal timing susceptibility of the optical sampling modules and their
internal clock recovery trigger signals usually increase the horizontal timing
jitter when external electromagnetic fields are applied. For fields up to 3 V/m,
the increase in the horizontal high-frequency RMS jitter is typically less than
3 ps RMS of jitter, added using the square-root-of-the-sum-of-the-squares
method. An example follows:
If an 80C01-CR operating in clock-recovery trigger mode exhibits 3.5 ps RMS of
edge jitter, with no EMC field applied and for an ideal jitterless input, then for
applied fields up to 3 V/m the edge jitter, degradation would typically result in a
total RMS jitter of:
Jitter ≤ 3.5ps 2 + 3ps 2

= 4.61ps
