FEATURES

DESCRIPTION

■ 375ps propagation delay

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.

■ 1.6V output swings

■ Internal 75KΩ input pull-down resistors

■ Available in 8-pin SOIC package
