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.

MARKING DIAGRAM
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 50Ω to
