Method for a 3-port 1394 connector with an integrated 1394 hub

Disclosed is a method for a 3 port 1394 connector with an integrated 1394 hub. Benefits include improved functionality.

Background

         A 1394 connector is a bus standard with 4 (consumer electronics) or 6 pins (computers), operating at 400-MHz and also known as a FireWire connection.

Routing three 1394 data pairs (operating at 400 Mbps) to a 3-port 1394 connector jack at the rear input/output (I/O) panel on a motherboard is very difficult. As a result, a single 1394 port on the rear I/O panel is used.

Sufficient board space is not available to place a 1394 transceiver/arbiter chip plus the required passive components on the motherboard near the rear I/O panel. Supporting three 1394 ports in the rear I/O panel area requires sacrificing valuable routing area on the motherboard.

Conventionally, no products have three 1394 ports on the rear I/O panel.

General description

The disclosed method integrates a 3-port 1394 hub transceiver into the 1394 connector stack in a desktop motherboard. The key elements of the method include:

•         1394 connector with 3 jacks

•         4-Port 1394 transceiver, operating in repeater mode

•         Optional separate power and status LEDs per port

Advantages

         The disclosed method provides advantages, including:

•         Improved functionality due to integrating a 3-port 1394 hub transceiver into the 1394 connector stack in a desktop motherboard

•         Improved functionality due to providing three 1394 ports in a...
