Network interface

Fig.10: Example schematic of a RJ45 based network interface

• The RXn+, RXn- and TXn+, TXn- shall be routed as differential pairs.
• The impedance between the differential traces shall be 100 Ω.
• VGND [x1] and VGND [x2] are virtual grounds and should not be connected to other ground areas.
• VGND1 and VGND2 shall be designed as local ground areas.
• The Link Activity LEDs shall be referenced to 0V Us
• Spare- (R1-R4) - and EMI (R5-R8, C1-C4) -circuits should be adapted to EMI requirements of the application.
