These are worst case values that are estimated from simulation and not tested. The values in the table are simulated at
F
SYS
= 132MHz, VDD = 1.35V to 1.65V, VDDE = 3.0V to 3.6V, VDDEH = 3.0V to 3.6V, VDD33 and VDDSYN = 3.0V to 3.6V,
T
A
= TL to TH.
This parameter is supplied for reference and is not guaranteed by design and not tested.
Delay and rise/fall are measured to 20% or 80% of the respective signal.
Out delay is shown in
Add a maximum of one system clock to the output delay for delay with respect to system clock.
This parameter is guaranteed by characterization before qualification rather than 100% tested.
