Description
The RTL8304MB-CG is a low-power, 4-port Fast Ethernet switch controller from Realtek. It integrates four 10/100Mbps PHYs and supports auto-negotiation, auto-MDI/MDIX, and QoS prioritization. Key features include:
- 4-Port Switch: Supports 10/100Mbps Ethernet with auto-negotiation.
- Auto-MDI/MDIX: Eliminates the need for crossover cables.
- QoS Support: Prioritizes traffic via 802.1p VLAN tagging.
- Low Power: Optimized for energy-efficient designs.
- Compact Package: 48-pin LQFP for space-constrained applications.
Ideal for embedded systems, industrial controls, and networking peripherals, the RTL8304MB-CG simplifies Ethernet switching with minimal external components. Datasheets and reference designs are available from Realtek.
