NOTES:Transmit I/O Timing:
1. When a setup time is specified between an input and a clock, the setup time is the time in nanoseconds
from the 1.4 V point of the input to the 1.4-volt point of the clock.
2. When a hold time is specified between an input and clock, the hold time is the time in nanoseconds from
the 1.4 V 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 V point of the reference signal to the
1.4 V point of the output.
