Hi Sir,.

1.how` the TD_A_P/N definition in Table.6 mirror port configuration, if it was designed to RJ45 "PLUG" side ?

2. how`s the MDIO maximum clock definition ? is it correct for measurement 6ms/bit ?

  

  • Hi Philip,

    Mirror mode changes the polarity and reorders the port numbers as well.

    Pin # (48QFN) Mirror Mode Disabled Pin Assignment Mirror Mode Enabled Pin Assignment
    1 TD_P_A (A+) TD_M_D (D-)
    2 TD_M_A (A-) TD_P_D (D+)
    4 TD_P_B (B+) TD_M_C (C-)
    5 TD_M_B (B-) TD_P_C (C+)
    7 TD_P_C (C+) TD_M_B (B-)
    8 TD_M_C (C-) TD_P_B (B+)
    10 TD_P_D (D+) TD_M_A (A-)
    11 TD_M_D (D-) TD_P_A (A+)

    MDIO max frequency is 25MHz.
