RK3288 Hardware Design Guide
Fig 21-7
Network transformer must meet following conditions as shown in Fig 21-8:
Fig 21-8
21.2 PCB Layout
The whole layout must follow below principles:
The closer PHY has been put to RK3288, the EMI will be less, which means RGMII
trace is the shorter, EMI will be less, and it must be controlled within 15cm.
Better to place RJ45 is close to PHY, MDI trace should be as shorter as possible
，
and
it must be controlled within 12cm
，
as shown in Fig 21-9.
