Fire VT6306/L IEEE 1394 Link-Layer / PHY Chipset Solution

VT6306_The VIA Fire II VT6306/L is a complete single chip IEEE1394 solution that provides high-speed seamless plug and play connection to the latest IEEE 1394 enabled PC peripherals and consumer devices such as HDDs, printers, stereos and video cameras.

With the integration of the Link Layer Controller and Physical Layer (PHY), OEMs and motherboard manufacturers looking to add IEEE 1394 capabilities to their product lineup find it both more cost-efficient and simpler to design the single chip IEEE1394 solution onto a PCI adapter card or directly onto a motherboard.

The VIA Fire II VT6306/L provides direct connectivity between the PCI and 1394 serial buses. With three ports, the VIA Fire II VT6306/L is designed to provide scalability and manageability in IEEE 1394 network solutions for home networking and multiple PC access to a single internet connection. Each individual port detects connected device types and automatically configures data speeds to either 100, 200 or 400 Mbps, speeds well suited to multi-streaming I/O requirements. A programmable PCI power management mode (specification 1.1) shuts down power to unconnected ports while the sleep function maximizes power efficiency of connected ports. VIA Fire II’s feature set also is an ideal for implementation into IEEE 1394 repeater hubs.

Benefits of VIA 1394 VT6306/L

Simplicity: Provides a simple low cost interconnect system for multimedia applications such as video cameras, VCRs, stereos and PC peripherals.

Flexibilty: High bandwidth capability allows devices of varying speeds to operate on the same network.

Compatibility : Universal plug-and-play capability allows devices to be attached or removed from the system, even with the power on. No device driver installation necessary as full software driver support is included in Windows® 98 SE and Windows® 2000.

Economical: 1394 does not utilize precious host processor bandwidth as peripherals communicate directly with each other without burdening the host processor.
