MC10EL89
5V ECL Coaxial Cable Driver
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. Because of the larger output swings, the
device cannot be terminated into the standard −2.0 V. All of the DC
parameters are tested with a 50 W to −3.0 V load. The driver accepts a
standard differential ECL input and can run off of the Digital Video
Broadcast standard −5.0 V supply.
