Overview

The KSZ8081RNA/RND 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 KSZ8081RNA/RND is a highly-integrated PHY solution. It 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. The KSZ8081RNA/RND 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 KSZ8081RNA/RND uses a 25 MHz crystal to generate all required clocks, including the 50 MHz RMII reference clock output for the MAC. The KSZ8081RND is the version that takes in the 50 MHz RMII reference clock as the power-up default. To facilitate system bring-up and debugging in production testing and in product deployment, parametric NAND tree support enables fault detection between KSZ8081RNA/RND I/Os and the board. LinkMD TDR-based cable diagnostics identify faulty copper cabling. The KSZ8081RNA and KSZ8081RND are available in 24-pin, lead-free QFN packages.
