3.0 Functional Description
(Continued)
TWISTER was loaded with pseudo random data (PRBS-
23) approximating actual packet data encrypted via the
stream cipher algorithm. The typical peak-peak total jitter
resulting from the combination of the transmitter, cable
plant, and receiver is only 1.9ns Pk-Pk (MLT-3, room
temp., nominal Vcc) as illustrated in Figure 3-5. Because
the maximum eye opening is 8ns, The DP83223 has little
impact on the total jitter budget.
