  • Page 27: Component Placement Considerations

    5.6.1 Component Placement considerations Components placement can affect signal quality, emissions and can decrease EMI problems. If the magnetics are a discrete component than the distance from the connector RJ45 should be kept under 25mm of separation. To decrease EMI problems the distance between magnetics and Phy should be at least 25mm or greater to isolate the PHY from magnetics.
  • Page 28: Cable Transient Event And Phy Protection

    5.6.2 Cable Transient Event and PHY Protection Cable transient events are + and - DC surges that are induced across the transformer onto the PHY side of the TX+/- and RX+/- signals as shown in the figure below. The PHY side of the transformer should not contain any DC component other than the typical 3.3V pull-up on the center tap of the transformer for analog signal biasing.
  • Page 29: Phy Ethernet

    5V. D3 and D4 act the same way when the transient is across the RX+/- differential pair. The total capacitance seen by each differential pair must not exceed 50pF (25pF single ended). Figure 10 Recommended by ENGICAM: Diode array TVS, 4 CH, ESD, 3.3V Wurth Elektronik 824015043...
