RTL8367N-VB-CG

         Single-Chip 5-Port 10/100/1000M Switch Controller

                                                General Description

The RTL8367N-VB-CG is a QFN88, high-performance 5-port 10/100/1000M Ethernet switch with an integrated low-power 5-port Giga-PHY that supports 1000Base-T, 100Base-TX, and 10Base-T.

The RTL8367N-VB integrates all the functions of a high-speed switch system; including SRAM for packet buffering, non-blocking switch fabric, and internal register management into a single CMOS device. Only a 25MHz crystal is required; an optional EEPROM is offered for internal register configuration.

The embedded packet storage SRAM in the RTL8367N-VB features superior memory management technology to efficiently utilize memory space. The RTL8367N-VB integrates a 2K-entry look-up table with a 4-way XOR Hashing algorithm for address searching and learning.

        Features

• Single-chip 5-port 10/100/1000M non-blocking switch architecture
• Embedded 5-port 10/100/1000Base-T PHY
• Each port supports full duplex 10/100/1000M connectivity (half duplex only supported in 10/100M mode)
• Full-duplex and half-duplex operation with IEEE 802.3x flow control and backpressure
• Supports 9216-byte jumbo packet length forwarding at wire speed
  

        Applications

• 5-Port 1000Base-T Switch
  

RTL8316E-CG

         LAYER 2 16-PORT 10/100M SINGLE-CHIP SWITCH CONTROLLER

                                                General Description

The RTL8316E is Layer 2 16-port 10/100M switch controllers that integrate 16

MACs and 16 physical layer transceivers for 100Base-TX and 10Base-T operation.

        Features

• 16-port switch controller with memory and transceiver for 10Base-T and 100Base-TX
• Non-blocking wire-speed
• Compatible with IEEE 802.3/802.3u
• Built-in high efficiency SRAM for packet buffer, with 8K-entry lookup table
• Flow control fully supported
  • Half duplex: Back pressure flow control
  • Full duplex: IEEE 802.3x flow control
    
    
  
  

        Applications

• 16-port switch (10Base-T & 100Base-TX)
