18.5 System Interface AC Characteristics
The AC characteristics of the system interface depend upon the mode of the interface. While UTOPIA vs. POS-
PHY mode does not have an effect on the AC characteristics, Level 2 vs. Level 3 does. Therefore, there are two
tables: one for Level 2

18-1,
The input/output timing reference level for all signals is VDD/2.
Rise and fall times are measured at output side with the output unloaded. Rise time is measured from 20% to 80% V
is measured from 80% to 20% V
These times are met with a 30pF, 300 Ω load on the associated output pin.
