Circuit
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 1.6V
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 50to VCC – 3.0V instead of 50to VCC – 2.0V.
