Transceivers Handle Signal and Power Over a Single Coax Cable

EqcoLogic’s EQCO800SC transceiver circuit enables full duplex communication together with power transmission over a single, low cost coaxial (COAX) cable, at speeds of up to 1.25 Gbit/second and with cable lengths up to 100 m. It supports a number of key protocols including IEEE 1394b (FireWire), Ethernet (Fast and Gigabit), and LVDS. The transceiver circuit is designed for automotive applications, where it enables high performance and low cost networking with COAX cables and connectors in entertainment, information and driver assist applications.

The EqcoLogic device is also suited for industrial and security cameras where FireWire cameras have established a strong position. With the EQCO800SC circuit, low-cost, long haul connections can be made using pre-existing COAX infrastructure. This allows the conversion of an existing analog camera system (using 75 ohm COAX cabling) to digital without the need to re-lay cable. Installations with COAX cables and connectors are intrinsically flexible and can include slip rings to allow rotation, for example, of a camera platform.
