RTL8306MB-CG

The RTL8306MB-CG is a low-power, 6-port Fast Ethernet switch controller from Realtek. It integrates a 5-port 10/100M PHY and a 6th port that can be configured as either an MII/RMII interface for an external MAC or an additional PHY.
Key features:
- Supports auto-negotiation, auto-MDIX, and QoS (IEEE 802.1p).
- Includes VLAN, port mirroring, and broadcast storm protection.
- Operates at 3.3V with low power consumption.
- Compact 48-pin LQFP package.
Applications include embedded systems, industrial control, and cost-sensitive networking devices. The RTL8306MB-CG simplifies design by reducing external components while offering basic switch functionality.
For detailed specs, refer to Realtek’s datasheet.
