20025225
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)
RSKMD = ISI (Inter-symbol interference) + TPPOS(variance) + LVDS Source Clock Jitter (cycle to cycle)
Cable Skew—typically 10 ps–40 ps per foot, media dependent
Note 8: Refer to transmitter datasheet for Cycle-to-cycle LVDS Output jitter specification.
Note 9: ISI is dependent on interconnect length; may be zero. Pre-emphasis in the transimitter is used to reduce the ISI. Refer to transmitter datasheet for more
information.
