ISO3082: ISO15DWR, ADM2483BRWZ

Part Number: ISO3082

Hi,  

My customer is using IC ADM2483 for their measurement devices. 

Now they made the PCB layout using IC ISO3082 and ISO15DWR ( photo and schematic attached)

But there is a problem in communication. The communication with their host device is unstable. The data rate with ISO3082/15 are lower then data rate with ADM2483.

Here i am attaching the circuit diagrams and the time diagrams of communication.

Regards, Peter Cheremisov

    Hi Peter,

    Could you please share some description about the waveforms you have attached?
    I understand that the schematic shared is the ISO area of the design?
    Please let me know the details of the waveforms? Could you please mention where the waveform has been captured?
    Was it captured on RXD, TXD or the bus lines?

    Thanks and Regards,

    Hi Anand,

    The waveforms have been captured in the A and B line next to the IC. 

    On the waveforms shown input and output packages to  the device from PC and and back. 

    I hoped that this is well known issue that was solved. :(
