Engineering Information EqcoLogic NV Open your Eyes? EQCO875SC.3/ EQC850SC.3 Single Coax Transceiver for Fast Ethernet 1.1 Features ? Combined transmitter and receiver with an integrated equalizer to form a full-duplex bidirectional connection over a single 75? coax cable (EQCO875SC.3) or 50? coax cable (EQCO850SC.3) ? Compatible with FX version of Fast Ethernet ? Low Power - 205mW from single 3.3V supply ? Integrated termination resistors for low external discrete count ? Fully supports PoE based Power distribution over the coax, on top of the data signals ? 16-pin, 0.65mm pin pitch, 4mm QFN package ? Pb-free and RoHS compliant 1.2 Applications This solution is useful and economical for many markets and applications, including the following: ? Camera networks - Home Security, Surveillance, industrial/inspection, medical cameras ? Home Networking over coax infrastructure ? When Cat5 or Cat6 cabling is not available and existing 75? coax is not used for analogue TV signals. ? TV, STB, PVR connections including inter-room links 1.3 Typical Cable Lengths Version EQCO875SC range using RG11 RG6 (? 5mm) EQCO875SC.3 225m 150m Table 1: Typical Device Performance DS-EQCO875SC.3 (Ethernet)-2v0-2011-10-25 Page 1 of 11 ?2014 Eqcologic NV Engineering Information EqcoLogic NV Open your Eyes?

A sister product, the EQCO850SC.3 can achieve similar performance when used in 50? coaxial systems 1 The EQCO875SC.3 is ideally suited for Fast Ethernet connections over 75? coax cable at 125Mbps 2 data rate. The EQCO875SC.3 connects seamlessly to any FX -compliant physical layer controller (PHY). For correct operation the signals are expected to be 4B/5B encoded, DC balanced and to have a bit rate of 125 Mbps. This EQCO875SC.3 is useful and economical for connecting remote PoE enabled Fast Ethernet IP cameras and other Ethernet over Coax applications.
