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.
