The RTL8370N-VB-CG is an LQFP128 E-PAD, high-performance 8-port Gigabit Ethernet switch. The RTL8370N-VB features low-power integrated 8-port Giga-PHYs that support 1000Base-T, 100Base-T, and 10Base-T. The embedded packet storage SRAM in the RTL8370N-VB features superior memory management technology

该资料为压缩包，内有4个文件，包含“LAN_HUB”、“RTL8367N-CG-DataSheet-1.0 ”、“RTL8367N-VB vs. RTL8367N Pin Assignments Difference”以及“RTL8367N原理图”,资料都是网络论坛搜集的，原理图也打板验证过可行，因为RTL8367N这个款芯片是千兆傻瓜交换机芯片，所以基本硬件电路没问题，打板直接插上路由器和设备就可以ping通。

前言: 家里书房局域网，PC都是千兆口，但是桌上的TP-link8口交换机是百兆的，两台机器对传资料备份的时候，峰值只能在11M/s左右。于是便自己想着做一个5口的全千兆交换机，省的浪费了电脑千兆网卡的资源。定芯片，看了BCM和马维尔的，都是MAC+PHY的构架，最后定了RTL8367RB，5口集成千兆PHY的片子，还有2个GMI的管理口，可以升级做ROUTER用。 相比某宝上100的产品相比: 用料扎实，千兆口全部用Pulse jack的RJ45,全钽电容 方便使用，采用micro usb 5V供电，可以直接电脑usb取电使用 指示灯丰富，当前连接状态（千兆为绿色，百兆为橙色，十兆为红色），数据交换（绿色闪烁）。 可裁剪，方便转产降低成本 5口千兆交换机实物图: 5口千兆交换机电路截图:
