Notes on DS3 Transmit Interface Timing:
1. 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.
2. 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.
3. 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.
4. Maximum and minimum output propagation delays are measured with a 50
pF load on all the outputs.
