DESCRIPTION
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 VCC â2.0V.
All of the DC parameters are tested with a 50⦠to
VCC â3.0V load. The driver accepts a standard differential
ECL input and can run off of the digital video broadcast
standard â5.0V supply.
