RTL8196E Datasheet PDF Product Information

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.

The RTL8196E provides five ports (ports 0~4), integrated with fivephysical layer transceivers for 10Base-T and 100Base-TX. Each port of the RTL8196E may be configured as a LAN or WAN port. The RTL8196E supports flexible IEEE 802.3x full-duplex flow control and optional half-duplex backpressure control. 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 capableof Head-Of-Line blocking prevention.

L2 Switch


: 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 ofeach entry is provided and the aging time is around 300~450 seconds.

The RTL8196E supports IEEE 802.3az, also known as Energy Efficient Ethernet (EEE). IEEE 802.3az operates with the IEEE 802.3 Media Access Control (MAC) Sublayer to support operation in Low Power Idle mode. When the Ethernet network is in low link utilization, EEE allows systems on both sides of the link to save power. Green Ethernet power saving provides: link-on and dynamic detection of cable length, and dynamic adjustment of power required for the detected cable length. Thisfeature provides high performance with minimum power consumption. The RTL8196E also implements link-down power saving on a per-port basis, greatly cutting power consumption when the network cable is disconnected.
