EQCO-FW5001

1394b Dongles for Long-Distance Over Coaxial Cable Extend 1394b Links up to 60m with Power Over Cable Summary Microchip’s EQCO-FW7501 and EQCO-FW5001 are two extender solutions for the FireWire® serial bus, operating over 75Ω and 50Ω 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 target—such as camera or hard drive—over the coax cable. The Microchip coaxial extenders fully support IEEE 1394b standards. Implementation Our 1394b Over Coax dongles make it easy to implement long-distance FireWire-based applications. By taking advantage of coaxial cable’s secure shielding, our 1394b dongles can even be used in electrically noisy enviornments such as factories. The EQCO-FW7501 supports up to 60 meters of 75Ω coaxial cable; the EQCO-FW5001 supports up to 30m of 50Ω coaxial cable. In both cases, they operate at a datarate of up to 1.0 Gbit/s (S800). The dongles give users the flexibility to determine the best cable lengths for their applications. The transceiver contains an equalizer that is fully adaptive that adjusts to a variety of cable lengths as well as age and environmental conditions like temperature, without any need for programming. The dongles have a standard 1394b 9-pin connector on one end and a 75Ω BNC or 50Ω SMA connector on the opposite end. These dongles are ideal for laboratory and industrial applications, such as machine vision and factory 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 Coax Interface/Cable EQCO-FW5001: 50Ω EQCO-FW7501: 75Ω Power Over Cable Max.
