EL5170, EL5370
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 V
REF
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 -40C to +85C temperature range.
Features
Fully differential inputs and outputs
Differential input range 2.3V typ.
100MHz 3dB bandwidth at fixed gain of 2
1200V/s slew rate
Single 5V or dual 5V supplies
50mA maximum output current
Low power - 7.4mA per channel
Pb-Free Available (RoHS Compliant)
Applications
Twisted-pair drivers
Differential line drivers
VGA over twisted-pairs
ADSL/HDSL drivers
Single ended to differential amplification
Transmission of analog signals in a noisy environment

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-020C.
