Interface - Controllers

The DP83907VF is an interface controller designed to link between computing systems, ethernet networks, processors, and peripheral devices. It is used in a variety of computer systems, as well as a wide range of networking and communications applications. The DP83907VF includes support for both 10Mbps and 100Mbps operation, as well as support for WOL (Wake On LAN) and a variety of other interface protocols.

Application Field

The DP83907VF is a versatile Ethernet controller, and is used in a variety of applications. It is particularly well suited to applications that require fast data transfer speeds, such as networking and communications applications. It is an ideal choice for industrial applications, such as factory automation, remote monitoring and control, and other real-time control systems. The DP83907VF is also well suited for use in high-speed backplane systems.

Working Principle

The DP83907VF is based on an architecture that is designed to provide highspeed data transmission. The controller consists of an 8-bit processor, a single-chip Ethernet PHY and a host interface. The processor is responsible for the management of the data transfers between the Ethernet network and the host processor. The PHY provides the physical layer interface to the Ethernet network, while the host interface provides a connection to the host processor. The processor is also responsible for the management of the controller\'s power saving functions.

The DP83907VF is designed to support both 10Mbps and 100Mbps operation. When running in 10Mbps mode, the controller runs at 2.5V DC and supports full-duplex operation, providing both transmit and receive functions. In 100Mbps mode, the controller supports both half-duplex and full-duplex operation, with a single-direction data rate of up to 100Mbps.

The DP83907VF also supports WOL (Wake On LAN) for remote power management. WOL is a feature that allows a computer to be remotely powered up from a low power state, without the need for human intervention. This feature is particularly useful for server and other network management tasks.

The DP83907VF also supports a variety of other interface protocols, including ARP, TCP/IP stack, UDP, ICMP (Ping), SNMP, DHCP, and SMTP. These protocols allow the controller to communicate with a variety of network-enabled devices, such as apps, routers, switches, and other networking equipment.

Conclusion

The DP83907VF is a versatile interface controller, ideal for a variety of computer systems and networking applications. The controller supports both 10Mbps and 100Mbps Ethernet operation, as well as support for WOL. The controller is also capable of supporting a variety of interface protocols, allowing it to communicate with a wide range of network-enabled devices.
