TPS23880: TPS23880: EVM Sifos Results

Part Number: TPS23880

We use EVM TPS23880 4-pair port to test Sifos, but the test result of "Detection_Time_Tdet" is 750ms which over 802.3bt standard 500ms.

  • Hi Kevin,

    The 500ms spec is for detection time for a pairset, not the total detection time for both pairsets. From the actual waveform and datasheet, TPS23880 passes the 500ms spec. The problem is that the sifos is measuring the total detection time  for both pairsets. I replied to your email offline, so I am going to close this thread and continue the discussion offline. Thanks. 

    Best regards,

    Penny
