1 / 5 page © Semiconductor Components Industries, LLC, 2006 January, 2006 − Rev. 4 1 Publication Order Number: MC10SX1189/D MC10SX1189 Fibre Channel Coaxial Cable Driver and Loop Resiliency Circuit Description The MC10SX1189 is a differential receiver, differential transmitter specifically designed to drive coaxial cables. It incorporates the output cable drive capability of the MC10EL89 Coaxial Cable Driver with additional circuitry to multiplex the output cable drive source between the cable receiver or the local transmitter inputs. The multiplexer control circuitry is TTL compatible for ease of operation. The MC10SX1189 is useful as a bypass element for Fibre Channel-Arbitrated Loop (FC-AL) or Serial Storage Architecture (SSA) applications, to create loop style interconnects with fault tolerant, active switches at each device node. This device is particularly useful for back panel applications where small size is desirable. The EL89 style drive circuitry produces swings twice as large as a standard PECL output. When driving a coaxial 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 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 W to VCC − 3.0 V instead of 50 W to VCC − 2.0 V. Features • 425 ps Propagation Delay • 1.6 V Output Swing on the Cable Driving Output • Operation Range: VCC = 4.5 V to 5.5 V • 75 kW Internal Input Pull Down Resistors • >1000 V ESD Protection • Transistor Count = 102 • Pb−Free Packages are Available* Figure 1.
