Hi Experts,

When I use two ISO1176TEVM to test transmit and receive.

There is 2ns delay with 2 meters cable connection.

If I use 25 meters cable to connect with two EVM, there is no signal in receiver.

What is the longest cable length I should use for two ISO1176T/ISO3086T EVM to test ?

Thanks a lot.

Sorry for correct.
There is 250 ns delay with 25 meters cable length.
There is 120 ns delay with 2 meters cable length.

Hi Wang,

Thanks for posting your question on E2E.

What is the datarate you are using in your system? The max cable length will be bounded by the data rate along with some other parameters.

Best regards,
Dan

Hi Wang,
I haven't heard from you in a few days. Were you able to figure out the max cable length for your application?
Best regards,

Hi Wang,

I haven't heard from you in about a week. I'm going to assume you were able to solve your own issue. If this is not the case please either respond to this thread or create a new one. I would be happy to help support you with ISO1176T.
