The SY10EP89V is a differential fanout gate specifically
designed to drive coaxial cables. The device is especially
useful in digitial 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, while maintaining a
800mV (5V) or 700mV (3.3V) 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
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.
