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 V
CC
− 3.0 V
instead of 50 W to V
CC
− 2.0 V.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
