4 Port GbE Ethernet PHY with 1588

Overview

TopologyLAN / POE
Input voltage1 V
IC revisionC1

Description

The LAN8814 is a low-power, quad-port triple-speed (10BASE-T/100BASE-TX/1000BASE-T) Ethernet physical layer transceiver (PHY) that supports transmission and reception of data on standard CAT-5, as well as CAT-5e and CAT-6, unshielded twisted pair (UTP) cables.The LAN8814 supports industry-standard QSGMII (Quad Serial Gigabit Media Independent Interface) and Q-USGMII (Quad Universal Serial Gigabit Media Independent Interface) providing chip-to-chip connection to four Gigabit Ethernet MACs using a single serialized link (differential pair) in each direction.The LAN8814 supports high-accuracy timestamping functions to support IEEE-1588 solutions using Microchip Ethernet switches, as well as customer solutions based on SoCs and FPGAs. The LAN8814 also provides Synchronous Ethernet (SyncE) and TSN frame preemption support.

Features

  • One and two-step IEEE1588 time stamping
  • Quad-Port Gigabit Ethernet transceiver
  • Low-power operation
  • On-chip temperature monitor
