TEXAS INSTRUMENTS  DP83849CVS  以太网控制器, 100 Mbps, IEEE 802.3u, 3 V, 3.6 V, TQFP, 80 引脚

The is a PHYTER dual commercial temperature dual-port 10/100Mb/s Ethernet Physical-layer Transceiver a highly reliable feature rich device enabling Ethernet on the factory floor. It provides optimum flexibility in MPU selection by supporting both MII and RMII interfaces. In addition this device includes a powerful new diagnostics tool to ensure initial network operation and maintenance. In addition to the TDR scheme, commonly used for detecting faults during installation, NAONAL"s innovative cable diagnostics provides for real time continuous monitoring of the link quality. This allows the system designer to implement a fault prediction mechanism to detect and warn of changing or deteriorating link conditions. With the National Semiconductor continues to build on its Ethernet expertise and leadership position by providing a powerful combination of features and flexibility, easing Ethernet implementation for the system designer.
