when we recommended SN65LVCP204 to replace MC100EL11+MC10EP56DTG in Gigabit Interface.how to solve the incompatible issue about LVPECL level converting to VML level，could you share me any solution like converting circuit or device etc.，thank you very much。

    Jane,

    VML drivers are voltage-level compatible with LVPECL, and  the input of LVCP204 has the internal terminal to Vcm,  so you can use 0.1uF capacitor for ac-coupling.

    for data communication, need to pay attention to DC-balance.

    Regards,

    Jack
