LAN8742A中文资料10/100 Base-T/TX Ethernet Transceiver with Cable Diagnostics数据手册Microchip规格书

描述 Description

Microchip's LAN8742A/LAN8742Ai are the latest generation of low-power, 10/100 Fast Ethernet PHYs featuring Wake-On-LAN functionality, which provides additional system sleep modes for improved power savings. The LAN8742A/LAN8742Ai feature deterministic loop back delay, assuring real-time system performance as well as cable diagnostics which reduce network installation costs. These devices are available in both commercial (0°C to 70°C) and industrial (-40°C to 85°C) temperature ranges.The LAN8742A/LAN8742Ai are well-suited for Consumer, Embedded and Industrial applications. Additionally, these devices support auto-negotiation, auto-polarity correction, HP Auto-MDIX† and is compliant with IEEE 802.3 and 802.3u standards.†HP Auto-MDIX eliminates the need for special \"crossover\" cables when connecting LAN devices together.Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects. You can confidently submit your design materials in a secure and private setting, and our expert engineers will provide individualized feedback to enhance your design. MicroCHECK design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
