RTL8201BL /
RTL8201CL /
RTL8201CP
Hardwire Configuration network:
1. 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.
