Ethernet Transceivers

Microchip's 10/100/1000 Mbps Ethernet PHYs are high-performance, small-footprint, low-power 10Base-T/100Base-TX/1000Base-T transceivers designed specifically for today's consumer electronics, industrial and enterprise applications. These devices feature Energy-Efficient Ethernet (IEEE 802.3az) and Wake-On-LAN functionality, which provides system sleep modes for improved power savings. These devices have the industry's smallest footprint and consume up to 40% less power than existing transceivers. They have an integrated voltage regulator and ESD protection components to help reduce Bill of Material (BOM) costs.

The LAN874XA family features deterministic loop back delay, assuring real-time system performance as well as cable diagnostics which reduce network installation costs.
