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.

• 425ps Propagation Delay

• 1.6V Output Swing on the Cable Driving Output

• Single +5V operation

• 75kΩ Internal Input Pull Down Resistors

• >1000 Volt ESD Protection

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

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 t

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
