Cable Skew — typically 10 ps to 40 ps per foot, media dependent
TJCC — Cycle-to-cycle LVDS Output jitter (TJCC) is less than 100 ps (worse case estimate).
ISI is dependent on interconnect length; may be zero
See Applications Informations section for more details.
d = Tppos — Transmitter output pulse position (min and max)
f = TJCC — Cycle-to-cycle LVDS Output jitter (TJCC) is less than 100 ps (worse case estimate).
m = extra margin - assigned to ISI in long cable applications
