Description

The KSZ8081 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.

Key Features

  • Single-chip 10Base-T/100Base-TX IEEE 802.3 pliant Ethernet transceiver
  • MII interface support (KSZ8081MNX)
  • RMII v1.2 Interface support with a 50MHz reference clock output to MAC, and an option to input a 50MHz reference clock (KSZ8081RNB)
  • Back-to-back mode support for a 100Mbps 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 disable and enable option
