用两颗RTL8367S-CG 通过RGMII口调用内部寄存器地址,可以实现8电+2电+2光公用的功能,当然你也可以做8电+2光或者8电+2电,主要替代RTL8370MB-CG+RTL8211FD-CG*2,实测性能杠杠的,附件为其中一款的PCB设计图纸,如有疑问,请留言。


RTL8367S-CG
         LAYER 2 MANAGED 5+2-PORT 10/100/1000M SWITCH CONTROLLER
                                                General Description
The RTL8367S-CG is a LQFP-128, high-performance 5+2-port 10/100/1000M Ethernet switch featuring a low-power integrated 5-Port Giga-PHY that supports 1000Base-T, 100Base-TX, and 10Base-T.
For specific applications, the RTL8367S supports one extra interface that could be configured as RGMII/MII interfaces. The RTL8367S also supports one Ser-Des interface that could be configured as SGMII/HSGMII interfaces. The RTL8367S integrates all the functions of a high-speed switch system; including SRAM for packet buffering, non-blocking switch fabric, and internal register management into a single CMOS device.

        Features
  • Single-chip 5+2-port 10/100/1000M nonblocking switch architecture
  • Embedded 5-Port 10/100/1000Base-T PHY
  • Each port supports full duplex 10/100/1000M connectivity (half duplex only supported in 10/100M mode)
  • Extra Interface (Extension GMAC1) supports
    • SGMII (1.25GHz) Interface
    • High SGMII (3.125GHz) Interface
  • Extra Interface (Extension GMAC2) supports
    • Media Independent Interface (MII)
    • Reduced 10/100/1000M Media Independent Interface (RGMII)
  • Full-duplex and half-duplex operation with IEEE 802.3x flow control and backpressure

        Applications
  • 5-Port 1000Base-T Router with SGMII/HSGMII and/or MII/RGMII 8+2TIM图片20180813143000.png 8+2TIM图片20180813143020.png
