OVERVIEW

The VT6307 IEEE 1394 OHCI Host Controller provides high performance serial connectivity. It implements the Link and Phy

layers for IEEE 1394-1995 High Performance Serial Bus specification release 1.0 and 1394a-2000. It is compliant with 1394 Open

HCI 1.0 and 1.1 with DMA engine support for high performance data transfer via a 32-bit bus master PCI host bus interface.

The VT6307 supports 100, 200 and 400 Mbit/sec transmission via an integrated 2-port PHY. The VT6307 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 retry operations.

The VT6307 is ready to provide industry-standard IEEE 1394 peripheral connections for desktop and mobile PC platforms.

Support for the VT6307 is built into Microsoft Windows 98, Windows ME, Windows 2000, and Windows XP.
