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 eval board application note for details,
and contact your sales rep for ordering information.
