KSZ8091MNX/KSZ8091RNB
10Base-T/100Base-TX Physical Layer Transceiver
Revision 1.

General Description
The KSZ8091 is a single-supply 10Base-T/100Base-TX Ethernet physical-layer transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable.
The KSZ8091 is a highly-integrated PHY solution.
It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs, by integrating a low-noise
regulator to supply the 1.
2V core, and by offering a flexible 1.
8/2.
5/3.
3V digital I/O interface.
The KSZ8091MNX offers the Media Independent Interface (MII) and the KSZ8091RNB offers the Reduced Media Independent Interfa...
