The number of applications that require an Ethernet connection continues to expand. With the growing market demand, this is a changing application demand. Single-channel Ethernet is used in many applications where sufficient is now required, such as wireless remote control base stations and dual-port capabilities for industrial network redundancy or system management.
The DP83849IF is a highly reliable, feature-rich device ideal for industrial applications enabling Ethernet on the factory floor. The DP83849IF has two 10/100 ports for fully independent multiport applications. Country-unique port switching also allows both ports to be configured to provide fully integrated distance extension, media conversion, hardware-based failover, and port monitoring.
The DP83849IF supports MII and RMII interface MPU selection provides the best flexibility. The device also provides the flexibility to support copper and fiber media. In addition, the unit includes a powerful new diagnostic tool to ensure initial network operation and maintenance.
In addition to the Taiwan Depositary Receipt Program, commonly used for fault detection during installation, National Semiconductor's innovative cable diagnostics provide real-time continuous monitoring of link quality. This allows system designers to implement failure prediction mechanisms to detect and warn of changes or deterioration in link conditions.
With the DP83849IF, National Semiconductor Corporation continues to provide a combination of powerful features and flexibility to ease Ethernet implementation system designers, the foundation of their Ethernet expertise and leadership.
