1 / 8 page © Semiconductor Components Industries, LLC, 1999 December, 1999 – Rev. 1 1 Publication Order Number: MC10SX1190/D MC10SX1190 Product Preview 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 Ω to VCC – 3.0V instead of 50Ω to VCC – 2.0V. • 2.5 Gbps Operation • 425ps Propagation Delay • 1.4V Output Swing on the Cable Driving Output • PECL Mode: 3.0V to 5.5V VCC, with VEE = 0V • ECL Mode: 0V VCC, with VEE = –3.0V to –5.5V • 75kΩ Internal Input Pull Down Resistors • >1000 Volt ESD Protection 19 20 18 17 16 15 14 2 1 3 4567 VCC 13 8 VCC QR QR VEE DT DT VCC VEE DR DR VCC VCC QT QT VEE 12 9 11 10 VBB VEE SEL VCC Figure 1. 20-Lead TSSOP Pinout: (Top View) This document contains information on a product under development.
