250MHz Differential Twisted-Pair Drivers
The EL5171 and EL5371 are single
and triple 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 input
signal is single-ended and the outputs are always in
differential form.
On the EL5171 and EL5371, two feedback inputs provide
the user with the ability to set the gain of each device (stable
at minimum gain of one). For a fixed gain of two, please see
EL5170 and EL5370.
The output common mode level for each channel is set by
the associated VREF pin, which have a -3dB bandwidth of
over 50MHz. 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 EL5171 and EL5371 are specified for operation over the
full -40°C to +85°C temperature range.
