KSZ9031MNX - Gigabit Ethernet Transceiver

Datasheet Summary

Description

The KSZ9031MNX is a completely integrated triple speed (10Base-T/100Base-TX/1000Base-T) Ethernet Physical Layer Transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable.

Features

  • to facilitate system bring-up and debugging in production testing and in product deployment. Parametric NAND tree support enables fault detection between KSZ9031MNX I/Os and board. LinkMD® TDR-based cable diagnostic provides identification of faulty copper cabling. Remote and local loopback functions provide verification of analog and digital data paths. The KSZ9031MNX is available in a 64-pin, lead-free QFN package (See Ordering Information). Features.
  • Single-chip 10/100/1000 Mbps IEE.

KSZ9031MNX Gigabit Ethernet Transceiver with GMII / MII Support Data Sheet Rev. 0.13 General Description The KSZ9031MNX is a completely integrated triple speed (10Base-T/100Base-TX/1000Base-T) Ethernet Physical Layer Transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable. The KSZ9031MNX offers the industry standard GMII/MII (Gigabit Media Independent Interface / Media Independent Interface) for connection to GMII/MII MACs in Gigabit Ethernet Processors and Switches for data transfer at 1000 Mbps or 10/100 Mbps speed. The KSZ9031MNX reduces board cost and simplifies board layout by using on-chip termination resistors for the four differential pairs and by integrating an LDO controller to drive a low cost MOSFET to supply the 1.2V core.
