Web– Transparency window of each latch is large, ½ a clock cycle • The large transparency window means – Can borrow time naturally • Can have up to 1.5 cycle (if there was no skew) in some cycle, if the adjacent cycle only needs .5 w/o skewing clocks – Is insensitive to clock skew; for critical paths, data sets timing WebFigure 1). A more appropriate jitter definition would seem to be one for something called “jitter stew.” Jitter stew Jitter can best be defined as the sum total of skews, reflections, pattern-dependent interference, propagation delays, and coupled noise that degrade signal quality.
