IP1000A数据手册IC+中文资料规格书

描述 Description

The IP1000A is a truly 10/100/1000Mbps Gigabit Ethernet NIC single chip which it incorporates a 32-bit PCI interface wit bus master support. It is manufactured using standard digital CMOS process and contain all the active circuitry required to implement the physical layer functions to transmit and receive data on standard CAT5 unshielded twisted pair cable.\r
\r
The IP1000A is designed for use in a variety of applications including workstation NICs, and other systems utilizing a PCI bus.The IP1000A includes a 32-bit PCI bus interface, IEEE 802.3 compliant MAC, transmit and receive FIFO buffers, IEEE 802.3 compliant 10BASE-T, and 100BASE-FX PHY, IEEE 802.3z compliant 1000 BASE-T PHY, serial EEPROM interface, expansion ROM interface and LED drivers.\r
\r
The IP1000A supports features for use in \"Green PCs\" or systems where control over system power consumption is desired. The IP1000A supports several power down states, and the ability to issue \"wake event\" via reception of unique, user defined Ethernet frames. In addition, the IP1000A can assert a wake event in response to changes in the Ethernet link status.
