when i use the TM4C1294NCPDTI of TI communicate with 88E6190X of marvell with ethernet,because the space of pcb is very samll,so i used capacitance for isolation,but the TM4C1294NCPDTI 's differential pair need pull up to 3V3,but 88E6190X not need pull up,after checking the datasheet, i found that this connection called "connection between current mode phy and voltage mode phy",Please help to see, in order to ensure the reliable operation of the chip, how to design this part ,thaks
