The DP83820BVUW is a compact, high-performance, single-chip media access controller (MAC) for 10/100/1000 Mbps Ethernet networks. It is designed for high-performance, interoperable full- and half-duplex 10/100/1000 Mbps applications. The DP83820BVUW includes support for IPV4, UDP, and TCP, and provides throughput that is optimized for wire-speed operation on 10/100/1000 Mbps networks. The DP83820BVUW is ideal for applications such as home networks, consumer/small-business solutions, as well as IP cameras and digital video/audio broadcast devices.

The DP83820BVUW is a single-chip, high-performance integrated transceiver with a media access controller (MAC). It is compliant to IEEE 802.3 Ethernet standards and supports IEEE 802.1P/Q networking protocols. It also supports TCP/IP offload engine, FEC, and supports IEEE 802.3az energy efficient ethernet (EEE). It features an integrated frame buffer that allows for efficient transfer of data packets, as well as a mechanism for tag based priority for each packet. Additionally, it features two receive queues with two priority levels and four transmission queues that allow for a more equitable distribution of traffic. It also features direct memory access (DMA) and reduced latency for data transfer from the system’s main memory to the Ethernet transceiver.

The Working Principle of the DP83820BVUW is based on the Ethernet standard, which combines the MAC layer, data link layer, and physical layer that provides a means of reliably transferring data between two or more nodes on a network. The device implements the physical layer, which provides the physical interface between Ethernet devices. This layer handles data transmission and reception, as well as responsible for the synchronization and organization of the traffic. Additionally, the transceiver provides the Media Access Controller, which provides the logical and physical layer connectivity between the PC and the physical layer.

The DP83820BVUW provides the functionality of an Ethernet MAC plus switch control, allowing for quick and efficient switching of network traffic between the two or more ports. Additionally, the transceiver has support for high-level protocols such as IPV4 and UDP, as well as checksum and priority based packet transmission. Moreover, the DP83820BVUW supports wake-up frames, pause frames and EEE, which are necessary tools for helping in the efficient operation of a network.

The DP83820BVUW provides a high performance and cost-effective solution for applications such as home networks, consumer/small-business solutions, as well as IP cameras and digital video/audio broadcast devices. By providing an integrated MAC and switch controller that is compliant with IEEE Ethernet standards while at the same time providing the high performance and throughput optimized for 100/1000 Ethernet networks, the DP83820BVUW provides fast and reliable solutions for a variety of network applications.
