Device Overview

Summary

The SY10EL89 is a differential fanout gate specifically designed to drive coaxial cables. The device is especially useful in Digital Video Broadcast applications. For this application, since the system is polarity-free, each output of the device can be used as an independent driver.The driver boasts a voltage gain of approximately 40 and produces output swings twice as large as a standard ECL output. When driving a coaxial cable, proper termination is required at both ends of the line to minimize signal loss. The 1.6V output swings allow for termination at both ends of the cable while maintaining the required 800mV swing at the receiving end of the cable. Because of the larger output swings, the device cannot be terminated into the standard -2.0V. All of the DC parameters are tested with a 50Ω to -3.0V load. The driver accepts a standard differential ECL input and can run off the Digital Video Broadcast standard -5.0V supply.
