Microchip's LAN8740A, LAN8741A and LAN8742A are the latest generation of low-power, 10/100 Fast Ethernet PHYs featuring Energy Efficient Ethernet (IEEE 802.3az) and Wake-On-LAN functionality, which provides system sleep modes for improved power savings. The LAN874xA family features deterministic loop back delay, assuring real-time system performance as well as cable diagnostics which reduce network installation costs. All devices are available in both commercial (0° to 70°C) and industrial (-40° to 85°C) temperature ranges. The LAN874xA family is well-suited for set-top box, PVR/DVR, industrial and test/measurement instrumentation applications. Additionally, these devices support auto-negotiation, auto-polarity correction, HP Auto-MDIX† and are compliant with IEEE 802.3 and 802.3u standards. Microchip also offers its complimentary and confidential LANCheck® online design review services to customers who select our products for their application design-in.*
†HP Auto-MDIX eliminates the need for special "crossover" cables when connecting LAN devices together.
*The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
