ISO1050: Waveform judge

Part Number: ISO1050
Other Parts Discussed in Thread: ISO1044, ISO1042,

Hi,

Related to below waveform, can you find any problem?

This is a question from my customer and I think that there is no problem because math result waveform looks like normal.

Best Regards,

Kuramochi

    Hi Kuramochi-san,

    Yes, like you have mentioned, the match function is showing CANH-CANL difference as a clean waveform and hence, shouldn't be an issue. I see there is a lot of common-mode noise on CANH and CANL pins, I am not very sure if these lines indeed have such noise riding on the bus or if it is only a oscilloscope pick-up or a lab environment pick-up.

    Could you please share us customer schematic and PCB layout to review if everything is okay?

    ISO1050 is one of our older devices, if possible please do request customer to use our latest ISO CAN devices. ISO1042 and ISO1044 are our newer devices with significant improvements compared to ISO1050.

    Hi Kuramochi-san,

    Hopefully customer is able to remove the noise observed on CAN bus pins. I will go ahead and close this E2E post. If you believe the issue is not resolved yet then please do respond to this post. Thanks.
