DP83869HM: Diagnostics Features

Part Number: DP83869HM
Other Parts Discussed in Thread: DP83849ID, , DP83869

Hi Team,

A customer is currently using the extensive Link Diagnostics features of the DP83849ID, but now wants to move to a Gigabit PHY. From the datasheet, neither the DP83869HM or the DP83867x have such Cable Diagnostic features like the DP83849ID. Is this truly the case?



  • Hi Mihir,

    DP83869 only supports polarity reversal, cable swap (MDI vs MDIX) detection, and TDR..

    It does not support 100Mb Cable Length Estimation, Frequency offset relative to link partner, Cable Signal Quality Estimation, or Link Quality Monitor.
