摘要
论述了USB/以太网转换器的设计方法,主要采用USB转以太网控制芯片AX88772B进行了设计。该转换器的USB接口符合USB 2.0/1.1规范,支持基于IEEE802.3和IEEE802.3u规范的10/100M以太网功能。同时,AX88772B内置动态电源管理以降低在空载、低负载等状况下的功耗,提供极低功耗并支持网络远程唤醒特性的睡眠模式。
The design methods of general USB/Ethernet converters arc discussed. USB to Ethernet controller chip AX88772B is described. The converter＇s USB interface complies with USB 2.0/1.1 specification, and supports 1EEE 802. 3 and IEEE802. 3U standard 10/100 M Ethernet. The dynamic power management is embedded in AX88772B to reduce power consumption under the condition of no-load, low load and an ultra-low power consumption, and to support the remote wake-up feature of sleep mode
