 2011-11-16

富威集團代理產線Realtek整合最適用於桌上型電腦之WiFi/Lan方案,可同時滿足客戶於桌上型電腦設計上多項需求。

 

WiFi: 8188cus/8192cu-新一代WLAN USB dongle

Lan: RTL8111F-超高速乙太網路單晶片

 

WiFi: 8188cus/8192cu-新一代WLAN USB dongle

Realtek推出最新一代的WLAN USB dongle解決方案,8188cus和8192cu。將MAC,PHY,ADC/DAC、EEPROM、Tansceiver、PA等單元完全集成在一個IC裏。由於是高集成度IC,所以產品可以做成很小的size,同時因為能耗很小,極其省電,也為其在便攜設備的應用提供可能。

產品特性:

  • CMOS MAC, Baseband MIMO PHY and RF in a Single Chip ,including EEPROM,PA,RF switch,RF filter,ADC,DAC, etc.
  • 1x1/2x2 MIMO technology for extended reception robustness and exceptional throughput
  • 150Mbps receive PHY rate and 75Mbps transmit PHY rate using 20MHz bandwidth
  • 300Mbps receive PHY rate and 150Mbps transmit PHY rate using 40MHz bandwidth
  • Backward compatible with 802.11b/g devices while operating at 802.11n data rates
  • Complies with USB 2.0(8188cus/8192cu);
  • Complies with PCI Express Base Specification Revision 1.1 (8191CE)
  • Multiple BSSID feature allows the RTL8192CU-GR to assume multiple MAC identities when used as a wireless bridge
  • Supports Wake-On-WLAN via Magic Packet and Wake-up frame
  • Configurable Bluetooth coexistence Interface.
  • Maximum data rate 54Mbps in 802.11g, and 300Mbps in 802.11n

主要應用:

普通USB dongle 無線網卡/mini USB/在MID、STB等嵌入式應用的wifi module

 

Lan: RTL8111F-超高速乙太網路單晶片

Realtek RTL8111F超高速乙太網路單芯片,是全球首顆應用IEEE 802.3az 節能標準(Energy Efficient Ethernet: EEE) 所設計出高效能、低功耗的超高速乙太網路單芯片,支持PCI Express 1.1總線接口,並符合IEEE 802.3u技術為10/100Mbps乙太網和IEEE 802.3ab規格的千兆以太網路芯片,並嵌入一次性可編程(OTP)存儲器,以取代外部EEPROM(93C46/93C56/93C66)。

 

RTL8111F完全符合微軟NDIS5,NDIS6(IPv4, IPv6, TCP, UDP)的校驗和分割任務的卸載(Large send and Giant send)功能,並支持IEEE 802的IP層的優先級編碼和IEEE 802.1Q Virtual bridged Local Area Network(VLAN)。上述特點有助於降低CPU的利用率。

 

EEE針對乙太網路連結中沒有資料流量時制定了新的機制,而RTL8111F能在此時進入低耗電模式,將不需用到的傳送或接收端的電路關閉,直到有需要傳送或接收封包時才再度開啟,回到正常傳收模式。此新機制可以省掉不必要的耗電,讓能源能更有效的被利用。當乙太網路連結中沒有資料流量時,RTL8111F隨即進入EEE的低耗電模式,耗電量立刻減少達80%(僅約66mW,平常約為410mW),而目前市面上一般的網路單晶片,皆未具備此EEE低耗電模式功能。

 

以技術領先的優異條件,讓瑞昱不斷設計和開發出更具競爭力的産品,同時具備高性能並符合環保及節能需求的趨勢。由於產品的功能完善、效能優異以及節能省電的環保特色,使得瑞昱成為超高速乙太網路晶片解決方案中,最值得信賴的選擇。
