2. Input clocks with duty cycles other than 50% affect bus performance. Timing parameters affected by input clock duty cycle
are identified by (a) and (b). To recalculate the approximate bus timing values, substitute the following expressions in place
of 1/8 t
in the above formulas, where applicable:
CYC
(a) (1–dc) × 1/4 t
CYC
(b) dc × 1/4 t
CYC
Where:
dc is the decimal value of duty cycle percentage (high time).
