MC10SX1190 Fibre Channel Coaxial Cable Driver and Loop Resiliency Circuit
The MC10SX1190 is a differential receiver, differential transmitter specifically designed to drive coaxial cables. It incorporates the output cable drive capability of the MC10EP89 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 MC10SX1190 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 EP89 style drive circuitry produces swings approximately 70% larger than a standard PECL output. When driving a coaxial cable, proper termination is required at both ends of the line to minimize reflections. The 1.4V 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 to VCC - 3.0V instead of 50 to VCC - 2.0V.

1. 10SX circuits are designed to meet the AC specifications shown in the table after thermal equilibrium has been established. The circuit is mounted in a test socket or mounted on a printed circuit board and transverse air greater than 500lfm is maintained. 2. The differential propagation delay is defined as the delay from the crossing points of the differential input signals to the crossing point of the differential output signals. 3. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal. 4. Duty cycle skew is the difference between tPLH and tPHL propagation delay through a device. 5. Minimum input swing for which AC parameters are guaranteed. 6. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPP Min and 1.0V. 7. Data taken at VCC, nom = 3.3V.
