描述 Description

The Realtek RTL8370MB-CG is a TQFP176 E-PAD, high-performance 8+2-port Gigabit Ethernet switch. It integrates 8 low-power Giga-PHYs that support 1000Base-T/100Base-T/10Base-T.
For specific applications, the RTL8370MB supports two extra interfaces. Extension GMAC1 supports RGMII(3.3v/2.5v)/MII/TMII/RMII/SGMII/1000Base-X/100Base-FX, Extension GMAC2 supports RGMII(3.3v/2.5v/1.8v)/MII/TMII/RMII/HSGMII/SGMII/1000Base-X/100Base-FX. The RTL8370MB implements 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.
