150MHz Differential Twisted Pair Driver
The EL2141 is a very high bandwidth amplifier whose output
is in differential form, and is thus primarily targeted for appli-
cations such as driving twisted pair lines, or any application
where common mode injection is likely to occur. The input
signal can be in either single-ended or differential form, but
the output is always in differential form.
On the EL2141, two feedback inputs provide the user with
the ability to set the device gain, (stable at minimum gain of
two).
The output common mode level is set by the reference pin
(V_REF), which has a -3dB bandwidth of over 100MHz. Gen-
erally, this pin is grounded, but it can be tied to any voltage
reference.
The transmission of ADSL/HDSL signals requires very low
distortion amplification, so this amplifier was designed with
this as a primary goal. The actual signal distortion levels
depend upon input and output signal amplitude, as well as
the output load impedance. (See distortion data inside.)
Both outputs (V_OUT, V_OUTB) are short circuit protected to
withstand temporary overload condition.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are 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.
