This configuration shows Enable: Auto negotiation, Full duplex, 100Mbps, Link Down Power Saving, MII interface Disable: Isolate, Repeater mode 2. These seven configuration pins could be connected to VDD or GND directly. Place C14, C15, L1 close to PWFBOUT and place C16 close to PWFBIN. U1/pin14 U1/pin48 Place L2, C17, C18, C19 as close to each power pin as possible. 1. You could simply connect RESETB to PCI Reset. And just discard R30, R28, C20. 2. If Wake on Lan feature is needed, you have to supply power from auxiliary power for all LAN-related circuit including RTL8201BL/CL/CP and MAC. In this kind of application, discard R29 and retain other components for one resetting upon power up. This schematic sets PHY address to 00001b. You could set PHY address from 00001b to 11111b. But the LED polarity must matchs the respective PHYAD setting. Refer to datasheet's detailed description. RTL8201BL : R19(NC) RTL8201BL : R6(NC); C10(NC) RTL8201CL/CP : R6(0 ohm); C10(0.1uF) RTL8201CL/CP : R19(0 ohm) RTL8201BL : R5 (5.9K 1%) RTL8201CL/RTL8201CP : R5 (2K 1%) Connect to MAC which has MII interface R27 is reserved for 8201CL/CP LED Mode Change to compatible with BL R34 is reserved for ensuring 8201BL/CL/CP latch to UTP Mode. R35 is reserved for ensuring 8201CL/CP latch to normal operation mode.
