100MHz Differential Twisted-Pair Drivers
The EL5170 and EL5370 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 signal
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 VREF pin, which have a -3dB bandwidth of
over 70MHz. 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 EL5170 and EL5370 are specified for operation over the
full -40°C to +85°C temperature range.
