The AC characteristics of the UTOPIA Interface fulfill the standard of [1] and [2]. Setup and hold
times of the 50 MHz UTOPIA Specification are valid.
According to the UTOPIA Specification, the AC characteristics are based on the timing
specification for the receiver side of a signal. The setup and the hold times are defined with
regards to a positive clock edge, see )LJXUH .
Taking into account the actual clock frequency (up to the maximum frequency), the
corresponding (min. and max.) transmit side "clock to output" propagation delay specifications
can be derived. The timing references (tT5 to tT12) are according to the data found in 7DEOH 
to 7DEOH .
