450MHz Differential Twisted-Pair Drivers
The EL5173 and EL5373 are single and triple high
bandwidth amplifiers with a fixed gain of 2. They are
primarily targeted for applications such as driving twisted-
pair lines in component video applications. The inputs can
be in either single-ended or differential form but the outputs
are always in differential form.
The output common mode level for each channel is set by
the associated REF pin, which have a -3dB bandwidth of
over 190MHz. 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 EL5173 and EL5373 are specified for operation over the
full -40°C to +85°C temperature range.
