specifications. The F311 will function @ 1 GHz.
Note 5:
t
PS
describes opposite edge skews, i.e. the difference between the delay of a differential output signal pair
’
s LOW-to-HIGH and HIGH-to-LOW prop-
agation delays. With differential signal pairs, a LOW-to-HIGH or HIGH-to-LOW transition is defined as the transition of the true output or input pin.
Note 6:
t
OSLH
describes in-phase gate-to-gate differential propagation skews with all differential outputs going LOW-to-HIGH; t
OSHL
describes the same con-
ditions except with the outputs going HIGH-to-LOW.
Note 7:
t
OST
describes the maximum worst case difference in any of the t
PS
, t
OSLH
or t
OST
delay paths combined.
Note 8:
The skew specifications pertain to differential I/O paths.
