MC10EL89 5 V ECL Coaxial Cable Driver Description The MC10EL89 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 independent 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.
6 V output swings allow for termination at both ends of the cable, while maintaining the required 800 mV swing at the receiving end of the cable.
