DATASHEET

450MHz Differential Twisted-Pair Drivers
EL5173, EL5373
Features
The EL5173 and EL5373 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 can be in either single-ended or
differential form but the outputs are always in differential form.
• Fully differential inputs and outputs
The output common mode level for each channel is set by the
associated REF pin, which has a -3dB bandwidth of over
190MHz. Generally, these pins are grounded but can be tied to
any voltage reference.
• 1100V/µs slew rate (EL5373)
All outputs are short circuit protected to withstand temporary
overload condition.
The EL5173 and EL5373 are specified for operation over the
full -40°C to +85°C temperature range.
• Differential input range ±2.3V
• 450MHz 3dB bandwidth at fixed gain of 2
• 900V/µs slew rate (EL5173)
• Single 5V or dual ±5V supplies
• 40mA maximum output current
• Low power - 12mA 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

Description of Operation and
Application Information
Product Description
The EL5173 and EL5373 are wide bandwidth, low power and
single/differential ended to differential output amplifiers. They
have a fixed gain of 2. The EL5173 is a single channel
differential amplifier. The EL5373 is a triple channel
differential amplifier. The EL5173 and EL5373 have a -3dB
bandwidth of 450MHz while driving a 200 differential load.
The EL5173 and EL5373 are available with a power-down
feature to reduce the power while the amplifiers are disabled.
Input, Output and Supply Voltage Range
The EL5173 and EL5373 have been designed to operate with a
single supply voltage of 5V to 10V or split supplies with its total
voltage from 5V to 10V. The amplifiers have an input common
mode voltage range from -4.5V to 3.4V for ±5V supply. The
differential mode input range (DMIR) between the two inputs
is from -2.3V to +2.3V. The input voltage range at the REF pin is
from -3.3V to 3.7V. If the input common mode or differential
mode signal is outside the above-specified ranges, it will cause
the output signal to become distorted.
The output of the EL5173 and EL5373 can swing from -3.3V to
3.6V at 200 differential load at ±5V supply. As the load
resistance becomes lower, the output swing is reduced.
logic signal is relative to VS+ pin. Letting the EN pin float or
applying a signal that is less than 1.5V below VS+ will enable
the amplifier. The amplifier will be disabled when the signal at
EN pin is above VS+ - 0.5V.
Output Drive Capability
The EL5173 and EL5373 have internal short circuit protection.
Its typical short circuit current is ±55mA. If the output is
shorted indefinitely, the power dissipation could easily
increase such that the part will be destroyed. Maximum
reliability is maintained if the output current never exceeds
±60mA. This limit is set by the design of the internal metal
interconnect.
Power Dissipation
With the high output drive capability of the EL5173 and EL5373,
it is possible to exceed the +125°C absolute maximum junction
temperature under certain load current conditions. Therefore, it
is important to calculate the maximum junction temperature for
the application to determine if the load conditions or package
types need to be modified for the amplifier to remain in the safe
operating area.
The maximum power dissipation allowed in a package is
determined according to Equation 1:
T JMAX – T AMAX
PD MAX = -------------------------------------------- JA
Differential and Common Mode Gain
Settings
Where:
As shown in the “Simplified Schematic” on page 9, since the
feedback resistors RF and the gain resistor are integrated with
200 and 400, the EL5173 and EL5373 have a fixed gain of
2. The common mode gain is always one.
• TAMAX = Maximum ambient temperature
Driving Capacitive Loads and Cables
The EL5173 and EL5373 can drive 16pF differential capacitor
in parallel with 200 differential load with less than 3.5dB of
peaking. If less peaking is desired in applications, a small
series resistor (usually between 5 to 50) can be placed in
series with each output to eliminate most peaking. However,
this will reduce the gain slightly.
When used as a cable driver, double termination is always
recommended for reflection-free performance. For those
applications, a back-termination series resistor at the
amplifier’s output will isolate the amplifier from the cable and
allow extensive capacitive drive. However, other applications
may have high capacitive loads without a back-termination
resistor. Again, a small series resistor at the output can help to
reduce peaking.
Disable/Power-Down
The EL5173 and EL5373 can be disabled and placed their
outputs in a high impedance state. The turn-off time is about
1.2µs and the turn-on time is about 100ns. When disabled, the
amplifier’s supply current is reduced to 40µA for IS+ and
2.5µA for IS- typically, thereby effectively eliminating the power
consumption. The amplifier’s power-down can be controlled by
standard CMOS signal levels at the ENABLE pin. The applied

• TJMAX = Maximum junction temperature
• JA = Thermal resistance of the package
The maximum power dissipation actually produced by an IC is
the total quiescent supply current times the total power supply
voltage, plus the power in the IC due to the load, or as
expressed in Equation 2:
V O

PD = i   V STOT  I SMAX +  V STOT – V O   ------------

(EQ. 2)
Where:
VSTOT = Total supply voltage = VS+ - VSISMAX = Maximum quiescent supply current per channel
VO = Maximum differential output voltage of the
application
RLD = Differential load resistance
ILOAD = Load current
i = Number of channels
By setting the two PDMAX equations equal to each other, we
can solve the output current and RLOAD to avoid the device
overheat.

Power Supply Bypassing and Printed Circuit
Board Layout
As with any high frequency device, a good printed circuit board
layout is necessary for optimum performance. Lead lengths
should be as short as possible. The power supply pin must be
well bypassed to reduce the risk of oscillation. For normal
single supply operation, where the VS- pin is connected to the
ground plane, a single 4.7µF tantalum capacitor in parallel
with a 0.1µF ceramic capacitor from VS+ to GND will suffice.
This same capacitor combination should be placed at each
supply pin to ground if split supplies are to be used. In this
case, the VS- pin becomes the negative supply rail.
For good AC performance, parasitic capacitance should be
kept to minimum. Use of wire-wound resistors should be
avoided because of their additional series inductance. Use of
sockets should also be avoided if possible. Sockets add
parasitic inductance and capacitance that can result in
compromised performance. Minimizing parasitic capacitance
at the amplifier’s inverting input pin is very important. The
feedback resistor should be placed very close to the inverting
input pin. Strip line design techniques are recommended for
the signal traces.
