MC10EL89

5V 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. 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.
