Back-to-Back Mode – 100Mbps Copper Repeater / Media Converter
Two KSZ8051MNL/RNL devices can be connected back-to-back to form a 100Base-TX to 100Base-TX copper repeater.
A KSZ8051MNL/RNL and a KSZ8041FTL can be connected back-to-back to provide a low cost media converter solution.
Media conversion is between 100Base-TX copper and 100Base-FX fiber. On the copper side, link up at 10Base-T is not
allowed, and is blocked during auto-negotiation.

MII Back-to-Back Mode (KSZ8051MNL only)
In MII Back-to-Back mode, a KSZ8051MNL interfaces with another KSZ8051MNL, or a KSZ8041FTL to provide a
complete 100Mbps copper repeater, or media converter solution, respectively.
The KSZ8051MNL devices are configured to MII Back-to-Back mode after power-up or reset with the following:
Strapping pin CONFIG[2:0] (pins 18, 29, 28) set to ‘110’
A common 25MHz reference clock connected to XI (pin 9)
MII signals connected as shown in the following table.
