GENERAL DESCRIPTION
The RTL8196E-CG is an integrated System-on-a-Chip (SoC) Application Specific Integrated Circuit (ASIC) L2 5-Port Ethernet switch. An RLX4181 CPU is embedded and the clock rate can be up to 400MHz. To improve computational performance, a 16Kbyte I-Cache, 8Kbyte D-Cache, 16Kbyte I-MEM, and 8Kbyte D-MEM are provided. A standard 5-signal P1149.1 compliant EJTAG test interface is supported for CPU testing and software development. For full-duplex, standard IEEE 803.3x flow control will enable pause ability only when both sides of UTP have auto-negotiation ability and have enabled pause ability. The RTL8196E also provides optional forced mode IEEE 802.3x full-duplex flow control. Based on optimized packet memory management, the RTL8196E is capable of Head-Of-Line blocking prevention. L2 Switch FEATURES
: The RTL8196E contains a 1024-entry address look-up table with a 10-bit 4-way XOR hashing algorithm for address searching and learning. Auto-aging of each entry is provided and the aging time is around 300~450 seconds.
