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 50Ω to
VCC – 3.0V instead of 50Ω 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.
