High frequency AC electricals are guaranteed by design and characterization. All outputs loaded with 50ý to V
Output-to-output skew is measured between outputs under identical transitions.
Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and with no skew of the edges at the
respective inputs. Part-to-part skew includes variation in t
signal.
