1.2.7 VT6307L PCI 1394a Integrated Host Controller<br />

1.2.7.1 Overview<br />

The VT6307L IEEE 1394 OHCI Host Controller prov<strong>id</strong>es high performance serial connectivity. It implements the<br />

Link and Phy layers for IEEE 1394-1995 High Performance Serial Bus a specification release 1.0 and 1394a P2000. It<br />

is compliant with 1394 Open HCI 1.0 and 1.1 with DMA engine support for high performance data transfer via a 32bit<br />

bus master PCI host bus interface.<br />

The VT6307L supports 100, 200 and 400 Mbit/sec transmission via an integrated 2-port PHY. The VT6307L services<br />

two types of data packets: asynchronous and isochronous (real <strong>tim</strong>e). The 1394 link core performs arbitration<br />

requesting, packet generation and checking, and bus cycle master operations. It also has root node capability and<br />

performs retry operations.<br />

The VT6307L is ready to prov<strong>id</strong>e industry-standard IEEE 1394 peripheral connections for desktop and mobile PC<br />

platforms. Support for the VT6306 is built into Microsoft Windows 98, Windows ME, and Windows 2000.<br />

1.2.7.2 Integrated 400 Mbit 2-Port PHY<br />

Supports provisions of IEEE 1394-1995 Standard for High Performance Serial Bus and the P1394a P2000.<br />

Fully interoperable with IEEE Std 1394-1995 devices<br />

Prov<strong>id</strong>es two 1394a fully compliant cable ports at 100 / 200 / 400 Mbit per second<br />

Host notification of PHY LinkOn events<br />

Full 1394a P2000 Support includes:<br />
