The RTL8393M-VC is a 52-port 10/100/1000M Managed Ethernet MAC Switch Controller. It supports 13 pairs of 5Gbps QSGMII to connect to external 52 ports Gigabit Ethernet PHY transceivers.
There are two mode selections in RTL8393M-VC. One is 48 10/100/1000BASE-T + 4 combo 10/100/1000BASE-T/SFP the other one is 48 10/100/1000BASE-T + 2 SGMII/100Base-FX/1000Base-X
The RTL8393M-VC is embedded with a up to 700MHz MIPS-34Kc CPU. It supports a 32-bit data bus, 32Mbyte SPI flash (3-byte mode) or 64MB SPI flash (4-byte mode), and 256M-Byte DDR3 SDRAMs (maximum). It is also embedded a 96KB SRAM can be used for time-sensitive application
RTL8393M-VC is 104 Gbps switch capacity
