Notes on Input 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. It is recommended that the transition time on all clock inputs is less than 15
ns.
Notes on Output Timing:
1. 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.
2. Maximum and minimum output propagation delays are measured with a 100
pF load on all the outputs for the UTOPIA interface, and 50 pF load on
microprocessor and TL_CLK outputs, and 25 pF on every other output.
3. Output tristate delay is the time in nanoseconds from the 1.4 Volt point of the
reference signal to the point where the total current delivered through the
output is less than or equal to the leakage current.
