Ethernet PHY ICs provide the physical-layer transceiver for 10/100/1000 Mbps wired network connectivity.
Product Overview
An Ethernet PHY (physical layer) IC connects a MAC (Media Access Controller) to the physical twisted-pair cable, performing encoding/decoding, clock recovery, and auto-negotiation for 10BASE-T, 100BASE-TX, and 1000BASE-T links. Low-power RMII/RGMII PHYs are widely used in embedded and industrial networking. Newfly supplies verified Ethernet PHY ICs (LAN8720-class, DP83848-class, KSZ-class) with cross-reference and BOM-matching support for production sourcing.
