KSZ8021RNL / KSZ8031RNL
10Base-T/100Base-TX PHY with RMII Support
General Description
Features
The KSZ8031RNL is a single-supply 10Base-T/100BaseTX Ethernet physical layer transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable.
The KSZ8031RNL is a highly-integrated, compact 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 1.8/2.5/3.3V digital I/O interface support.
The KSZ8031RNL offers the Reduced Media Independent Interface (RMII) for direct connection to RMII-compliant MACs in Ethernet processors and switches.
