Visão Geral
Description
The RTL8238B-VB-GR is a highly integrated Ethernet PHY transceiver from Realtek, designed for 10/100/1000Mbps applications. It supports RGMII/MII interfaces, auto-negotiation, and energy-efficient Ethernet (EEE).
Key features:
- Single-chip solution for Gigabit Ethernet.
- Supports copper and fiber interfaces.
- Low power consumption with advanced power management.
- Compliant with IEEE 802.3 standards.
Applications include switches, routers, and industrial networking. The VB-GR variant typically indicates specific packaging (e.g., QFN) and RoHS compliance.
For detailed specs, refer to Realtek’s datasheet.
