Product Description

General Description
The KSZ8051 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 KSZ8051 is a highly integrated, compact 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 KSZ8051MNL offers the Media Independent Interface (MII) and the KSZ8051RNL offers the Reduced Media Independent Interface (RMII) for direct connection with MII/RMII compliant Ethernet MAC processors and switches.
Features
• Single-chip 10Base-T/100Base-TX IEEE 802.3 compliant Ethernet Transceiver
• MII Interface support (KSZ8051MNL)
• RMII v1.2 Interface support with 50MHz reference clock output to MAC, and option to input 50MHz reference clock (KSZ8051RNL)
• Back-to-Back mode support for 100Mbps copper repeater or media converter
• 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 for reliable detection and correction for straight-through and crossover cables with disable and enable 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 for identification of faulty copper cabling
• Parametric NAND Tree support for fault detection between chip I/Os and board.
• 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 (5mm x 5mm) QFN package
Applications
• Game Console
• IP Phone
• IP Set-top Box
• IP TV
