AC Timing Diagrams
C — Setup and Hold Time (Internal data sampling window) defined by Rspos (receiver input strobe position) min and max
Tppos — Transmitter output pulse position (min and max)
RSKM ≥ Cable Skew (type, length) + LVDS Source Clock Jitter (cycle to cycle) + ISI (Inter-symbol interference)
See Applications Information section for more details.
C — Setup and Hold Time (Internal data sampling window) defined by Rspos (receiver input strobe position) min and max
RSKMD ≥ TPPOSvariance (d) + TJCC (output jitter)(f) + ISI (m)

Cable Skew — typically 10 ps–40 ps per foot, media dependent
Cycle-to-cycle LVDS Output jitter (TJCC) is less than 100 ps (worse case estimate).
ISI is dependent on interconnect length; may be zero
d= Tppos — Transmitter output pulse position (min and max)
f= 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
