Mil1394 Dual Quad-Port Repeater Hub Overview
The Mil1394 Dual Quad-Port Repeater Hub (FW-MIL-2X4HUB19-400T-2) is a dual quad-port, transformer-coupled S200β and S400β capable repeater/hub with 9-pin IEEE-1394b connectors.
This 1U 19 inch rack mount repeater provides a cost and space-efficient solution, enabling consolidation of two, quad-port hubs into one chassis. Extend laboratory cable distances, isolate expensive 1394 test equipment from modules during testing, and better manage up to four directly-connected devices in a single hub.
Mil1394 Dual Quad-Port Repeater Hub Features
- Two bus (Channel) each with four Mil1394 and IEEE-1394-2008 compliant ports
- Four Beta only ports (eight total) per hub supporting:
- S100β (122.88Mb/s)
- S200β (245.76Mb/s)
- S400β (491.52Mb/s)
- Configurable maximum connection speeds of:
Standard 9-pin IEEE-1394b connectors for each port
Activity LEDs for each hub to indication bus traffic is present
Implemented using Texas Instrument’s TSB41BA3 PHY Layer IC
Mil1394 Dual Quad-Port Repeater Hub Applications
- Extend cable distances in laboratory and flight test applications
- Isolate expensive 1394 test equipment from modules during environmental and EMI testing
- Enable connection of four devices directly into a single hub
Mil1394 Dual Quad-Port Repeater Hub Benefits
- Consolidation of two 4-port hubs into a single 1U 19 inch rack mount chassis
- Mil1394 active transformer-coupled ports allows for longer cable lengths
- 4-Port hub allows direct connection of up to four devices
