Note 5: For driver delay measurements, R
points are set between the driver’s input logic threshold and the output
transition to the zero crossing (t
Note 6: For receiver delay measurements, C
set between the receiver’s input logic threshold and the output transition
to standard TTL/CMOS logic threshold (t
to 0.8V).
Note 7: Data rate operation guaranteed by slew rate, short-circuit current
and propagation delay tests.
