1394b Dongles for Long-Distance Over Coaxial Cable Extend 1394b Links up to 60m with Power Over Cable Summary Microchips EQCO-FW7501 and EQCO-FW5001 are two extender solutions for the FireWire serial bus, operating over 75 and 50 coaxial cables respectively. Each unit contains a 1394b transceiver (EQCO875SC-HS or EQCO850SC-HS) that support full-duplex FireWire 800 (S800) data transfer rates (1.0 Gbit/s) over a single coax cable. The transceiver includes an adaptive equalizer that supports a cable length of up to 60m. In addition to this long-distance, full-duplex data transmission, these devices allow power to be transmitted simultaneously from the host side to a targetsuch as camera or hard driveover the coax cable. The Microchip coaxial extenders fully support IEEE 1394b standards. The dongles give users the flexibility to determine the Implementation best cable lengths for their applications. The transceiver Our 1394b Over Coax dongles make it easy to implement contains an equalizer that is fully adaptive that adjusts to long-distance FireWire-based applications. By taking a variety of cable lengths as well as age and environmental advantage of coaxial cables secure shielding, our conditions like temperature, without any need for 1394b dongles can even be used in electrically noisy programming. The dongles have a standard 1394b 9-pin enviornments such as factories. connector on one end and a 75 BNC or 50 SMA connector on the opposite end. The EQCO-FW7501 supports up to 60 meters of 75 coaxial cable the EQCO-FW5001 supports up to 30m of These dongles are ideal for laboratory and industrial 50 coaxial cable. In both cases, they operate at a data- applications, such as machine vision and factory rate of up to 1.0 Gbit/s (S800). automation, where robust cabling is required. They can also be used with high-flex, small-diameter coaxial cable with rotating joints, if necessary, for applications where multiple rotations are required.Technical Specifications IEEE 1394b Interface Connector 9-Pin 1394b Coax Interface/Cable EQCO-FW5001: 50 50 rated SMA EQCO-FW7501: 75 75 rated BNC Power Over Cable Max.
