f
max with Internal Feedback 1/(
t
su+
t
cf)
Note:
t
cf is a calculated value, derived by subtracting
t
su from
the period of fmax w/internal feedback (
t
cf = 1/
f
max -
t
su). The
value of
t
cf is used primarily when calculating the delay from
clocking a register to a combinatorial output (through registered
feedback), as shown above. For example, the timing from clock
to a combinatorial output is equal to
t
cf +
t
pd.
f
max with No Feedback
Note:
f
max with no feedback may be less than 1/(
t
wh +
t
wl). This
is to allow for a clock duty cycle of other than 50%.
