Hi Team,

My customer is considering use ISOW7841 as interface for sensor, which data rate will be 9.6kbps or 12.8kbps.

ISOW7841 have Max data rate at 100Mbps, is there any min data rate limitation for ISOW7841? Which means, can customer use ISOW7841 at 9.6kbps or 12.8kbps data rate?

Thanks.

Hi Jo,

Thanks for reaching out.

There is no restriction on the minimum input signal frequency, it can operate even with from DC signal (0Hz) upto 100Mbps. Hence, operating it at 9.6kbps or 12.8kbps is not a problem.

ISOW7841 is our first-generation ISOW device, I would recommend customer to consider our latest and second-generation ISOW device, ISOW7741 which offers significant performance improvements. Please see below E2E post for the differences between ISOW7841 and ISOW7741. Thanks.
