Measured in a terminated 50Ω transmission line environment.

And still maintain 80% amplitude.

And still maintain a propagation delay variation (measured at the differential crossing points) of

TPD ± 30 ps.

This parameter is guaranteed by characterization. It is not production tested against the

specification limit.

This parameter is guaranteed by design and characterization. It is production tested against

tester limits of Tpd = 550 ps ± 200 ps.

This parameter is guaranteed by design and characterization. It is production tested against

a tester limit of 160 ps.
