The KSZ8081RNACA is a 10BASE-T/100BASE-TX Ethernet physical-layer transceiver with a single supply for data transmission and reception over CAT-5 unshielded twisted pair (UTP) cable.
The KSZ8081RNACA is a PHY solution with a high level of integration. It uses on-chip termination resistors for the differential pairs, integrates a low-noise regulator to supply the 1.2V core, and supports 1.8/2.5/3.3V digital I/O interfaces, which minimizes board cost and simplifies board architecture.
For direct connection to RMII-compliant MACs in Ethernet processors and switches, the KSZ8081RNACA supports the Reduced Media Independent Interface (RMII).
