Notes
1. K28.7 pattern is applied differentially at point A as shown in AC test circuit (see ï¬gure).
2. Total jitter does not include the signal source jitter. Total jitter (TJ) = (14.1 Ã 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 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 the AC test circuit (see ï¬gure).
