Coaxial Cable Driver
The MC10EL/100EL89 is a differential fanout gate specifically
designed to drive coaxial cables. The device is especially useful in Digital
Video Broadcasting applications; for this application, since the system is
polarity free, each output can be used as an idependent driver. The driver
boasts a gain of approximately 40 and produces output swings twice as
large as a standard ECL output. When driving a coaxial cable, proper
termination is required at both ends of the line to minimize signal loss. The
1.6V output swings allow for termination at both ends of the cable, while
maintaining the required 800mV swing at the receiving end of the cable.
Because of the larger output swings, the device cannot be terminated into
the standard –2.0V. All of the DC parameters are tested with a 50Ω to
–3.0V load. The driver accepts a standard differential ECL input and can
run off of the Digital Video Broadcast standard –5.0V supply.
• 375ps Propagation Delay
• 1.6V Output Swings
• 75kΩ Internal Input Pulldown Resistors
• >1000V ESD Protection

1. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ≈40.
2. 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 VPPmin and 1V . The lower end of the CMR range is dependent on VEE and is
equal to VEE + 2.5V.
