MC10EL89D

MC10EL89 5V ECL Coaxial Cable Driver The MC10EL89 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 boasts a 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 1.6 V output swings allow for termination at both ends of the cable, while maintaining the required 800 mV swing at the receiving end of the cable. Because of the larger output swings, the device cannot be terminated into the standard −2.0 V. All of the DC parameters are tested with a 50  to −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. http://onsemi.com MARKING DIAGRAMS* 8 SOIC−8 D SUFFIX CASE 751 8 1 HEL89 ALYW G 1 Features • • 375 ps Propagation Delay 1.6 V Output Swings PECL Mode Operating Range: VCC = 4.2 V to 5.7 V with VEE = 0 V NECL Mode Operating Range: VCC = 0 V with VEE = −4.2 V to −5.7 V Internal Input Pulldown Resistors Pb−Free Packages are Available 8 TSSOP−8 DT SUFFIX CASE 948R 8 1 1 DFN8 MN SUFFIX CASE 506AA Q0 1 8 HL89 ALYWG G 5A M G G • • • • 1 4 VCC Q0 2 7 D Q1 3 6 D A L Y W M G = Assembly Location = Wafer Lot = Year = Work Week = Date Code = Pb−Free Package (Note: Microdot may be in either location) *For additional marking information, refer to Application Note AND8002/D.
