Product Description Of KSZ8091RNAIA

KSZ8091RNAIA 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.
KSZ8091RNAIA is a highly-integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs, 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.
