550MHz Differential Twisted-Pair Drivers
The EL5174 and EL5374 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 in either single-ended or differential form but
the outputs are always in differential form.
On the EL5174 and EL5374, 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
EL5173 and EL5373.
The output common mode level for each channel is set by
the associated 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 EL5174 is available in an 8-pin SO package and
EL5374 is available in a 28-pin QSOP package. All specified
for operation over the full -40°C to +85°C temperature range.
