사양
RTL8367RBI‑VH‑CG is a high-performance Layer 2 managed Gigabit Ethernet switch chip designed by Realtek, integrating five built-in 10/100/1000M copper PHY transceivers and two configurable uplink MAC ports for flexible network expansion.
Part Number Definition
RTL8367RBI is the core model of the switch series with enhanced anti-interference and extended function sets. VH refers to the hardware version with complete register configuration and rich peripheral control options. CG stands for LQFP128 package with exposed thermal pad, shipped in tape-and-reel packaging for automatic SMT assembly.
Port and Protocol Specifications
The chip is equipped with 5 RJ45 ports with integrated Gigabit PHY, fully conforming to IEEE 802.3, 802.3u, 802.3ab and 802.3az energy-saving Ethernet specifications. All ports support automatic rate and duplex negotiation, together with Auto-MDI/MDIX cable pin auto-correction to avoid distinguishing straight and crossover network cables. Two additional GMAC ports can be switched between RGMII, MII and SGMII modes, which can be connected to main control processors, Wi-Fi master chips or optical module transceivers to realize fiber access. It adopts non-blocking wire-speed forwarding architecture, supports store-and-forward transmission and jumbo frames up to 9216 bytes. The built-in 2K MAC address table supports automatic learning, aging and static address binding to meet basic layer 2 forwarding demands.
Management and QoS Features
It supports port-based VLAN, 802.1Q tagged VLAN, port isolation and broadcast storm suppression. An 8-level QoS queue system distributes transmission priority based on port mark, 802.1p tag and DSCP field to prioritize audio, video and key service data. Other practical functions include port mirroring, ingress and egress bandwidth limitation, spanning tree protocol for loop prevention and cable fault diagnosis. Device parameters can be loaded from external EEPROM when powered on, and register access and configuration can be realized through SMI management bus. A certain number of ACL entries are reserved for data packet filtering and access permission control.
Power and Clock Configuration
The chip takes 3.3V as the I/O power supply, and the internal voltage regulator generates core working voltage to simplify external power circuit design. Only one external 25MHz crystal oscillator is needed to provide system reference clock. Multiple low-power modes are available to reduce power consumption when ports are disconnected or idle. Each port is matched with LED pins to display link state, connection speed and data transmission activity.
Package and Mechanical Parameters
The packaging type is 128-pin LQFP with exposed thermal pad. The moisture sensitivity level is MSL 3, and reflow soldering must be finished within 168 hours after opening the vacuum package. The exposed pad on the bottom optimizes heat dissipation during long-time high-load data forwarding and improves operational stability.
Compliance and Environmental Index
The working temperature range is 0℃ ~ +70℃. The product is lead-free and fully compliant with RoHS and REACH standards without restricted hazardous materials. Optimized EMC design strengthens anti-electromagnetic interference ability, adapting to household networking equipment and light industrial control network environments.
