MC10EP89DG

3.3/5V ECL同轴电缆驱动器

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 to VCC-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.
