1.2.7 VT6307L PCI 1394a Integrated Host Controller
1.2.7.1 Overview
The VT6307L 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 a specification release 1.0 and 1394a P2000. 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 VT6307L supports 100, 200 and 400 Mbit/sec transmission via an integrated 2-port PHY. The VT6307L 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 VT6307L is ready to provide industry-standard IEEE 1394 peripheral connections for desktop and mobile PC
platforms. Support for the VT6306 is built into Microsoft Windows 98, Windows ME, and Windows 2000.
1.2.7.2 Integrated 400 Mbit 2-Port PHY
Supports provisions of IEEE 1394-1995 Standard for High Performance Serial Bus and the P1394a P2000.
Fully interoperable with IEEE Std 1394-1995 devices
Provides two 1394a fully compliant cable ports at 100 / 200 / 400 Mbit per second
Host notification of PHY LinkOn events
Full 1394a P2000 Support includes:
