    Ethernet Compliance Test I210-AT 10Base-T/100Base-TX

    Andrija Community Member

      Hi

       

      I want to run Ethernet Compliance Tests 10/100Mbps with I210-AT.

      Are there any information available? I can not find anything in the datasheet.

      E.g. create 100Mbps MLT-3 Random Test Pattern.

       

      I can only find Test Mode Register Bits (15:13) in 1000Base-T Control Register (Page 0, Register 9) for Gigabit.

       

      What is the purpose of 100 MB test select bits 3:2 of Copper Specific Control Register 3 - Page 0, Register 23 ?

      What can I do with the PRBS Control - Page 26, Register 23 ?

       

      Thanks for your help

              Hello Carlos,

               

              I work also with the i210 component and I search to perform the ethernet compliant test to 10/100BASE-T too. I've just subscribe myself in when I saw your post.

              I looked at the chapters you refered to in your reply, but it's still not clear to me how to enable a test mode pattern generation.

              I found inside the datasheet "12.5.7 Physical Layer Conformance Testing"  that for "Output Amplitude, Rise and Fall Time (10/100 Mb/s), Symmetry and Droop (1 GbE). For the I210,

              use the appropriate PHY test waveform."

              Where are the  "test waveform" for the 10/100 Mb/s? it's not described inside this datasheet. Should we generate them outside of the component? there is only a Test mode for the 1000BASE-T, do the component have a similary mode for the speed lower?

               

              I have another component on my product which use a TI PHY -DP38xx, and they have a document which explains how to configure the component for conformance testing, do you have something close to this document ? (http://www.ti.com/lit/an/snla239a/snla239a.pdf )

               

              For the testing tools we have a Teledyne/Lecroy automated Ethernet test suite on which we directly plug our DUT and run the conformance test.

               

              Thanks for pointing me in the right direction.
