Notes:
1. When a set-up time is specified on differential LVDS signals between an input and a clock, the set-up time is the time in nanoseconds from
the cross-over point of the input to the cross-over point of the clock.
2. When a hold time is specified on differential LVDS signals between an input and a clock, the hold time is the time in nanoseconds from the
cross-over point of the clock to the cross-over point of the input.
