DESCRIPTION
The AZ10EL89 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 has a voltage gain of approximately 40 and produces
an output swing twice as large as 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 swing allows 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 V
CC
-2.0V. All of the DC parameters are tested with a
50鈩?to V
CC
-3.0V load. The driver accepts a standard differential ECL input and can run off of the Digital Video
Broadcast standard -5.0V supply. Under open input conditions (pulled to V
EE
) internal input clamps will force the
Qn output LOW.
NOTE: Specifications in ECL/PECL tables are valid when thermal equilibrium is established.
