FEATURES
Technologies, Inc. We Connect OVERVIEW It has a PCI host bus interface. The VT6305 supports 100, 200 and 400 Mbits/sec transmission. Depending on transmission speed, the Link / PHY connection is provided through a 2- / 4- / 8-bit interface operating at 50 MHz. The VT6305 services two types of data packets: asynchronous and isochronous (real time). The 1394 link core performs arbitration requesting, packet generation and checking, and bus cycle master operations. It also has root node capability and performs cycle and retry operations. The VT6305 is ready to provide industry-standard IEEE 1394 peripheral connections for desktop and mobile PC platforms. Support for the VT6305 will be built into Microsoft Windows 98 (Memphis) and Windows NT 5.0.
