SMD IC RTL8211E-VB-CG

Specialized Overview

The RTL8211E-VB-CG is a single-chip Gigabit Ethernet transceiver manufactured by Realtek. It integrates a 10/100/1000BASE-T PHY and an integrated MAC, supporting full-duplex operation at all speeds. The device features an RGMII interface for connection to host processors and supports Energy Efficient Ethernet (EEE) per IEEE 802.3az standards. It operates with a 3.3V supply voltage and includes built-in diagnostics and link status indicators.

Specialized Feature Summary

• Integrates physical layer transceiver and media access controller on a single chip
• Supports reduced Gigabit Media Independent Interface for processor connectivity
• Enables low-power standby modes compliant with energy efficiency standards

Specialized Applications

• Network interface adapters for personal computers and workstations
• Ethernet switches and hubs requiring compact form factors
• Embedded systems utilizing UTP physical connections
• Media Access Units (MAU) for network infrastructure

Specialized Procurement Notes

Verify the component authenticity through official Realtek channels or authorized distributors. Confirm the package marking matches the specific suffix VB-CG to ensure correct pinout and electrical characteristics. Request original manufacturer documentation to validate performance specifications against counterfeit risks.

Specialized Selection Notes

Select this component when a combined PHY and MAC solution is required to reduce board space. Ensure the host processor supports the RGMII interface timing requirements. Verify that the system design accommodates the necessary clock frequencies and impedance matching for high-speed data lines.

Specialized Part Context

This part belongs to the Realtek RTL8211 family of Gigabit Ethernet controllers. The E variant typically denotes specific feature sets or revisions within the product line. The VB-CG suffix indicates the specific package type and environmental compliance rating defined by the manufacturer.

Specialized Replacement Considerations

Direct replacements include other variants within the RTL8211 series such as the RTL8211F or RTL8211B, provided interface compatibility is maintained. Cross-vendor alternatives require significant schematic and firmware modifications due to differing register maps and interface protocols.
