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) + Source Clock Jitter (cycle to cycle) (Note 9) + ISI (Inter-symbol interference) (Note 10)

Cable Skew — typically 10 ps–40 ps per foot, media dependent

Note 9: Cycle-to-cycle jitter is less than 250 ps at 85 MHz.

Note 10: ISI is dependent on interconnect length; may be zero.
