MC10EP89DTR2G

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 VCC-2.0 V. All of the DC parameters are tested with a 50 ohms toVCC-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.
