DP83825I: The Issue of Ti DP83825I Ethernet PHY cannot output IEEE 802.3 compliance test waveform of 10Base-T Standard Test Script,and cannot work with new script PHY registers 0x16

Part Number: DP83825I

Can you please try setting register 0x16 to enable either digital or PCS loopback?

=> After to add the suggestion of  Ti E2E website suggestion as below test result for 10Base-T

 There are many items of 10Base-T cannot measurement since Ti Ethernet PHY DP83825I of  10Base-T Standard Test script cannot work as below.

0x16 = 0x710f

    Hello Romeo,

    Could you clarify if you were able to run the digital or PCS loopback?

    Thanks,

    10Base-T Standard script for PHY Registers 0x16 =>0X710f

    Could you clarify if you were able to run the digital or PCS loopback?

    ==>setup  PHY Registers 0x16 =>0X710f  => I  think both enable digital or PCS loopback,am I right?

    Thanks.

    I knew the Table 35. BISCR_Register Register Field Descriptions" of the datasheet of DP83823i.

    But it does not work to see crrurrect Waveform output of 10 Base-TX Standard test script.

    It is not helpful for resolve my my LAN SI issue of 10 Base-T as below:.

    Thank you.

    Hello Romeo,

    Sorry for the delayed response. I was looking at your attachment. This part does not support 10BASE-T, it supports 10BASE-Te it looks like you are following the right steps to configure for 10BASE-Te can you confirm that you are testing for 10BASE-Te and not 10BASE-T your document mentions both.

    Thanks,

    Vibhu
