Note 1: K28.7 pattern is applied differentially at point A as shown in Figure 1.
Note 2: Total jitter does not include the signal source jitter. Total jitter (TJ) = (14.1 RJ + DJ) where RJ is random RMS jitter and DJ
is maximum deterministic jitter. Signal source is a K28.5± pattern (00 1111 1010 11 0000 0101) for the deterministic jitter
test and K28.7 (0011111000) or equivalent for the random jitter test. Residual jitter is that which remains after equalizing
media-induced losses of the environment of Figure 1 or its equivalent. The deterministic jitter at point B must be from media-
induced loss and not from clock source modulation. Jitter is measured at 0V at point C of Figure 1.
Note 3: Using K28.7 (0011111000) pattern.
Note 4: AC specifications are guaranteed by design and characterization.
