ISOW1044: PCB Trace length

Venkata Rami Reddy Vempati

Part Number: ISOW1044

Hi Team
Regarding the PCB trace length of output lines CANH and CANL, the maximum trace length for the ISOW1044DFMR is not specified in the datasheet.

Could you please provide the recommended trace length

Regards,

Rami Reddy.

Hi Rami,

Thanks for reaching out.

The CAN bus length is always user defined and max length limitations come from ISO 11898 standard (physical layer requirements)

You can refer this appnote for reference: https://www.ti.com/lit/an/slla270/slla270.pdf?ts=1767595902368&ref_url=https%253A%252F%252Fwww.google.com%252F
