NOTES: Receive 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-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 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 propagation delays are measured with a 30 pF load when operating OIF-SPI3 standard 104
MHz. Over-clocked rates of 125 MHz or higher are measured using a load of 20 pF.
