Note1: The UTOPIA specification AC Characteristics are based on the timing specification for the receiver side of a
signal. In the case where the MT90225/226 is driving a signal (sending side), the input setup to the (next) clock can
be derived using the worst case period of the actual clock used. t
that receives the output from the MT90225/226.
