KSZ8081MLX 10Base-T/100Base-TX Physical Layer Transceiver Revision 1.3 Features General Description Single-chip 10Base-T/100Base-TX IEEE 802.3 The KSZ8081MLX is a single-supply 10Base-T/ compliant Ethernet transceiver 100Base-TX Ethernet physical-layer transceiver for MII interface support transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable. Back-to-back mode support for 100Mbps copper repeater The KSZ8081MLX is a highly-integrated, compact solution. MDC/MDIO management interface for PHY register It reduces board cost and simplifies board layout by using configuration on-chip termination resistors for the differential pairs, by integrating a low-noise regulator to supply the 1.2V core, Programmable interrupt output and by offering 1.8/2.5/3.3V digital I/O interface support. LED outputs for link, activity, and speed status indication On-chip termination resistors for the differential pairs The KSZ8081MLX offers the Media Independent Interface (MII) for direct connection with MII-compliant Ethernet Baseline wander correction MAC processors and switches. HP Auto MDI/MDI-X to reliably detect and correct straight-through and crossover cable connections with The KSZ8081MLX provides diagnostic features to facilitate disable and enable option system bring-up and debugging in production testing and in product deployment. Parametric NAND tree support Auto-negotiation to automatically select the highest link- enables fault detection between KSZ8081MLX I/Os and up speed (10/100Mbps) and duplex (half/full) the board. Micrel LinkMD TDR-based cable diagnostics Power-down and power-saving modes identify faulty copper cabling. LinkMD TDR-based cable diagnostics to identify faulty The KSZ8081MLX is available in the 48-pin, lead-free copper cabling LQFP package (see Ordering Information).
