EQCO850SC.3-HS EQCO875SC.3-HS EQCO850SC.3-HS/EQCO875SC.3-HS Single-Coax Transceiver for LVDS and Gigabit Ethernet Applications Features Introduction Combined Transmitter and Receiver with an The EQCO850SC-HS single-coax transceiver is Integrated Equalizer to Form a Full-Duplex designed to simultaneously transmit and receive Bidirectional Connection over a Single 50 Coax signals on a single 50 coax cable. A sister product, Cable (EQCO850SC-HS) or 75 Coax Cable the EQCO875SC-HS, can achieve similar performance (EQCO875SC-HS) when used in 75 coaxial systems. Internal LVDS Termination Resistors for Low The EQCO850SC.3-HS works for 50 coax External Discrete Count applications and the EQCO875SC.3-HS works for 75 Allows Power and Data Signal Distribution Over coax applications. Everything is the same between both Coax parts except the part number, the coax resistance and Single 3.3 V Supply the characteristic impedance of transmission lines and connectors between the chip and the edge of the 16-Pin, 0.65 mm Pin Pitch, 4 mm QFN Package boards. Refer to Section3.0 Application Pb-Free and RoHS Compliant Information for information about the typical application circuit. Applications This solution is useful and economical for many markets and applications, including the following: Camera Networks - Home Security, Surveillance, Industrial/ Inspection, Medical Cameras Coax Cable Distribution Infrastructure TABLE 1: TYPICAL EQUALIZATION PERFORMANCE FOR EQCO850SC.3-HS EQCO850SC.3-HS range using Bit Rate RG174 ( 2.8 mm) RTK ( 2.8 mm) RG58 (5 mm) 500 Mbps 25m 40m 50m 1 Gbps 15m 25m 30m Note: For other cable types, the length that can be reached in full-duplex may have a maximum of -12 dB insertion loss at 625 Mhz, for a bit rate of 1.25 Gbps. Equalizer performance works up to much higher levels in half- duplex. For lower bit-rates, slightly longer cable lengths can be achieved.
