MC10EP89/D
MC10EP89
3.3V / 5V ECL Coaxial
Cable Driver
Description
The MC10EP89 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 produces swings 70% larger than 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 (5 V) and 1.4 V (3.3 V)
swing allow for termination at both ends of the cable, while
maintaining a 800 mV (5 V) and 700 mV (3.3 V) swing at the
receiving end of the cable. Because of the larger output swings, the
device cannot be terminated into the standard V
CC
-2.0 V. All of the
DC parameters are tested with a 50 W to V
CC
-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.
