Lan: RTL8111F-超高速乙太网络单芯片

Realtek RTL8111F超高速乙太网络单芯片,是全球首颗应用IEEE 802.3az 节能标准(Energy Efficient Ethernet: EEE) 所设计出高效能、低功耗的超高速乙太网络单芯片,支持PCI Express 1.1总线接口，并符合IEEE 802.3u技术为10/100Mbps乙太网和IEEE 802.3ab规格的千兆乙太网络芯片,并嵌入一次性可编程（OTP）存储器，以取代外部EEPROM（93C46/93C56/93C66）。

RTL8111F完全符合微软NDIS5，NDIS6(IPv4, IPv6, TCP, UDP)的校验和分割任务的卸除(Large send and Giant send)功能,并支持IEEE 802的IP层的优先级编码和IEEE 802.1Q Virtual bridged Local Area Network（VLAN）。上述特点有助于降低CPU的利用率。

EEE针对乙太网络链接中没有数据流量时制定了新的机制，而RTL8111F能在此时进入低耗电模式，将不需用到的传送或接收端的电路关闭，直到有需要传送或接收封包时才再度开启，回到正常传收模式。此新机制可以省掉不必要的耗电，让能源能更有效的被利用。当乙太网络链接中没有数据流量时，RTL8111F随即进入EEE的低耗电模式，耗电量立刻减少达80%（仅约66mW，平常约为410mW），而目前市面上一般的网络单芯片，皆未具备此EEE低耗电模式功能。

以技术领先的优异条件，让瑞昱不断设计和开发出更具竞争力的产品，同时具备高性能并符合环保及节能需求的趋势。由于产品的功能完善、效能优异以及节能省电的环保特色，使得瑞昱成为超高速乙太网络芯片解决方案中，最值得信赖的选择。
