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 differential.
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 V_REF 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.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations). Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
