Note that output data may go invalid
before
rising edge of the clock. To clock data in reliably, you need to sample data, for
example, 2 ns before rising edge of clock.

Timing figure given takes 50% margin for noise and uncertainty on pin capacitance. Simulated clock-to-data, not taking noise
effects into account is 2.7 ns.
