MC10SX1189 Fibre Channel Coaxial Cable Driver and Loop Resiliency Circuit Description www.onsemi.com The MC10SX1189 is a differential receiver, differential transmitter specifically designed to drive coaxial cables. It incorporates the output FIBRE CHANNEL COAXIAL cable drive capability of the MC10EL89 Coaxial Cable Driver with additional circuitry to multiplex the output cable drive source between CABLE DRIVER AND LOOP the cable receiver or the local transmitter inputs. The multiplexer RESILIENCY CIRCUIT control circuitry is TTL compatible for ease of operation. The MC10SX1189 is useful as abypass element for Fibre Channel-Arbitrated Loop (FC-AL) or Serial Storage Architecture (SSA) applications, to create loop style interconnects with fault 16 tolerant, active switches at each device node. This device is 1 particularly useful for back panel applications where small size is SOIC16 desirable. CASE 751B05 The EL89 style drive circuitry produces swings twice as large as astandard PECL output. When driving acoaxial cable, proper termination is required at both ends of the line to minimize reflections. The 1.6 V output swings allow for proper termination at both ends MARKING DIAGRAM* of the cable, while maintaining the required swing at the receiving end of the cable. Because of the larger output swings, the QT, QT outputs are terminated into the thevenin equivalent of 50 to V 3.0 V CC 10SX1189G instead of 50 to V 2.0 V.
