Overview of KSZ8081MNXCA

The KSZ8081MNXCA 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 KSZ8081MNXCA 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.

The KSZ8081MNXCA offers the Media Independent Interface (MII) and the theKSZ8081MNXCA offers the Reduced Media Independent Interface (RMII) for direct connection with MII/RMII-compliant Ethernet MAC processors and switches. A 25 MHz crystal is used to generate all required clocks, including the 50 MHz RMII reference clock output for the KSZ8081MNXCA.

KSZ8081MNXCA Features

• Back-to-back mode support for a 100 Mbps copper repeater

• MDC/MDIO management interface for PHY register configuration

• Programmable interrupt output

• LED outputs for link, activity, and speed status indication

• On-chip termination resistors for the differential pairs

• Baseline wander correction

• HP Auto MDI/MDI-X to reliably detect and correct straight-through and crossover cable connections with disabling and enabling the option

• Auto-negotiation to automatically select the highest link-up speed (10/100 Mbps) and duplex (half/full)

• Power-down and power-saving modes

• LinkMD TDR-based cable diagnostics to identify faulty copper cabling

• Parametric NAND Tree support for fault detection between chip I/Os and the board

• HBM ESD rating (6 kV)

• Loopback modes for diagnostics

• Single 3.3V power supply with VDD I/O options for 1.8V, 2.5V, or 3.3V

• Built-in 1.2V regulator for core

• Available in 32-pin (5 mm × 5 mm) QFN package
