Microchip Technology LAN8814 4-Port Gigabit Ethernet Transceivers are low-power, quad-port triple-speed (10BASE-T/100BASE-TX/1000BASE-T) Ethernet physical layer transceiver (PHY) that provides transmission and reception of data on standard CAT-5, CAT-5e, CAT-6, and 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). These interfaces provide a chip-to-chip connection to four Gigabit Ethernet MACs using a single serialized link (differential pair) in each direction. The Microchip LAN8814 Transceivers deliver high-accuracy time-stamping functions to enable IEEE-1588 solutions using Microchip Ethernet switches and custom solutions based on SoCs and FPGAs. The LAN8814 additionally provides Synchronous Ethernet (SyncE) and TSN frame preemption support.
