1、1FN7491.3EL5178, EL5378700MHz Differential Twisted-Pair DriversThe EL5178 and EL5378 are single and triple high bandwidth amplifiers with an output in differential form. They are primarily targeted for applications such as driving twisted-pair lines in component video applications. The inputs can be
2、 in either single-ended or differential form but the outputs are always in differential form.On the EL5178 and EL5378, two feedback inputs provide the user with the ability to set the gain of each device (stable at minimum gain of 2). The output common mode level for each channel is set by the assoc
3、iated REF pin, which have a -3dB bandwidth of over 110MHz. Generally, these pins are grounded but can be tied to any voltage reference.All outputs are short circuit protected to withstand temporary overload condition.The EL5178 is available in 8 Ld MSOP and SOIC packages and EL5378 is available in a
