When a set-up time is specified between an input and a clock, the set-up time is the time in
nanoseconds from the 1.4 Volt point of the input to the 1.4 Volt point of the clock.
When a hold time is specified between an input and a clock, the hold time is the time in nanoseconds
from the 1.4 Volt point of the clock to the 1.4 Volt point of the input.
Output propagation delay time is the time in nanoseconds from the 1.4 Volt point of the reference
signal to the 1.4 Volt point of the output.
Output propagation delays are measured with a 50 pF load on the outputs except for the Level 3
interface output signals (TCA/TPA, STPA, RCA/RVAL, RDAT[31:0], RPRTY, RSOC/RSOP, REOP,
RERR, RMOD[1:0] and RSX) where the load is 30 pF.
Output tri-state delay is the time in nanoseconds from the 1.4 Volt of the reference signal to the point
where the total current delivered through the output is less than or equal to the leakage current.
