KSZ8081RNAIA 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.

KSZ8081RNAIA is a highly-integrated PHY solution. KSZ8081RNAIA reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs and by integrating a low-noise regulator to supply the 1.2V core, and by offering 1.8/2.5/3.3V digital I/O interface support.

KSZ8081RNAIA offers the Reduced Media Independent Interface (RMII) for direct connection to RMII-compliant MACs in Ethernet processors and switches. As the power-up default, the KSZ8081RNAIA uses a 25MHz crystal to generate all required clocks, including the 50MHz RMII reference clock output for the MAC.

KSZ8081RNAIA is available in 24-pin, lead-free QFN packages.
