K28.7 pattern is applied differentially at point A as shown in Figure 1.
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 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:
Stresses greater than those listed under MAX I MUM RAT-
INGS may cause permanent damage to the de vice. This is
a stress rating only and func tion al op er a tion of the device
at these or any other conditions above those indicated in
the operational sections of this spec i fi ca tion is not implied.
Exposure to absolute max i mum rating con di tions for ex-
