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.
