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

All of the DC parameters are tested with a 50Ω to

V

ECL input and can run off of the digital video broadcast

standard –5.0V supply.
