5. XCLK frequency must be 24x the line rate ±32 ppm when TJAT is free-
6. CTCLK can be a jittered clock signal subject to the minimum high and low
7. When a set-up time is specified between an input and a clock, the set-up
8. When a hold time is specified between an input and a clock, the hold time is
9. Setup, hold, and propagation delay specifications are shown relative to the
10. Output propagation delay time is the time in nanoseconds from the 1.4 Volt
11. Output propagation delays are measured with a 50 pF load on all outputs with
running or referenced to a derivative of XCLK. XCLK may be ± 100 ppm if an
accurate reference is provided to TJAT.

XCLK input frequency.
time is the time in nanoseconds from the 1.4 Volt point of the input to the 1.4
Volt point of the clock.
