AZ10EL89 PECL/ECL Coaxial Cable Driver www.azmicrotek.com DESCRIPTION FEATURES The AZ10EL89 is a differential fan-out gate specifically designed to drive coaxial cables. The device is especially useful in digital video applications. In such applications, each output can be used as an independent driver since the system is polarity free. • • • • The driver has a voltage gain of approximately 40 and produces an output swing twice as large as standard ECL output. The driver accepts a standard differential ECL input and can run off of the Digital Video Broadcast standard -5.0V supply.

AZ10EL89 ECL/PECL Coaxial Cable Driver ENGINEERING NOTES When driving a coaxial cable, proper termination is required at both ends of the line to minimize signal loss. The 1.6 V output swing allows 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 VCC 2.0V. All of the DC parameters are tested with a 50Ω to VCC -3.0V load. The driver accepts a standard differential ECL input and can run off of the Digital Video Broadcast standard -5.0V supply. Under open input conditions (pulled to VEE) internal input clamps will force the Q outputs LOW. 75Ω COAX AZ10EL89 0.1µF 75Ω 75Ω COAX 150Ω 150Ω 0.1µF 75Ω VEE Figure 2 – Termination Configuration www.azmicrotek.com +1-480-962-5881 Request a Sample 3 May 2012, Rev 2.0 Arizona Microtek, Inc.
