minimize EMI and reflections. Nevertheless, for the best jitter
performance when driving long cables, the faster speed
options may be preferable, even at lower data rates. The
faster output transitions deliver less variability (jitter) when
loaded with the large capacitance associated with long
cables. Figures 42, 43, and 44 detail the jitter performance of
the three speed options while driving three different cable
lengths. The figures show that under all conditions the faster
the edge rate, the better the jitter performance. Of course,
faster transitions require more attention to ensuring short
stub lengths, and quality terminations, so there are trade-offs
to be made. Assuming a jitter budget of 10%, it is likely
better to go with the slow speed option for data rates of
115kbps or less, to minimize fast edge effects. Likewise, the
medium speed option is a good choice for data rates
between 115kbps and 460kbps. For higher data rates, or
when the absolute best jitter is required, use the high speed
option.
Evaluation Board
An evaluation board, part number ISL41387EVAL1, is
available to assist in assessing the dual protocol IC’s
performance. The evaluation board contains a QFN
packaged device, but because the same die is used in all
packages, the board is also useful for evaluating the
functionality of the other versions. The board’s design allows
for evaluation of all standard features, plus the QFN specific
features. Refer to the evaluation board application note for
details and contact your sales rep for ordering information.
