TJA1043 - Delay Time

Pavithra_63 — Wed, 06 May 2026 05:56:36 GMT

Hello Team,

Currently in my CAN gateway system im measuring the - delay time from TXD to bus dominant, delay time from TXD to bus recessive, delay time from bus dominant to RXD, delay time from bus recessive to RXD.

CAN Baudrate - 2Mbps

In Datasheet i found only typical values mentioned for the above listed parameters.

Can you share the Maximum value for the same.

Additionally please find the measured timing results in My system.

Could confirm is the measured values is within the TJA1043 expected range? or else am i deviating??

Hi Pavithra

Normally we don't provide the data out of the datasheet but I will double check these for you and let you know later.

Hi Pavithra

Why is customer re-measuring these parameters, what problem do they try to solve?

Hi,

We are verifying the datasheet parameters in our CAN gateway as whole System.

Hi Pavithra

For your questions, indeed, only typical values are available for these parameters. That’s because the whole delay from TXD to RXD is also specified, with min and max (see attached datasheet and snapshot below).

Thanks!
