RTL8213B-CG

The RTL8213B-CG is a highly integrated Ethernet transceiver from Realtek, designed for 10/100/1000BASE-T applications. It supports IEEE 802.3az (Energy-Efficient Ethernet) and features auto-negotiation, crossover detection, and low power consumption.
Key features:
- Single-chip solution with PHY + magnetics (PoE-ready).
- Supports Gigabit Ethernet over CAT5/6 cables.
- RGMII/MII interface for flexible MAC connectivity.
- Advanced crosstalk & echo cancellation for signal integrity.
- Industrial-grade temperature range (-40°C to 85°C).
Commonly used in switches, routers, IP cameras, and industrial networking. The -CG suffix indicates a lead-free (RoHS-compliant) package.
