Description
An 802.11b/g/n PCIe Network Interface Controller refers to a network interface controller (NIC) that supports wireless connectivity based on the IEEE 802.11b, 802.11g, and 802.11n standards. It is designed to be installed on a computer’s Peripheral Component Interconnect Express (PCIe) expansion slot.
The PCIe NIC enables wireless communication between a computer and a Wi-Fi network, allowing the computer to connect to the internet or other devices wirelessly.
The Realtek RTL8192ER-CG is an 802.11bgn 2.4G single-chip that integrates Wireless LAN (WLAN) and a network PCIe controller. It combines a WLAN MAC, a 2T2R capable WLAN baseband, and WLAN RF in a single chip. The RTL8192ER-CG provides a complete solution for a high-throughput performance and low power consumption integrated wireless LAN device.
The RTL8196ER 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 five physical 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 capable of Head-Of-Line blocking prevention. […]
